This play can definitely not be classified as a romantic comedy. It belongs to a completely different species of drama, known as the ‘comedy of manners’ or artificial comedy. It follows the ancient classical comedies in observing at least two of the three unities of time, place and action.
Only the unity of action has been violated in this play because it has multiple plots.
In The Rivals we observe three distinct plots:
a) the Absolute Lydia love affair,
b) Faulkland Julia love affair and,
c) Mrs. Malaprop Sir Lucius affair
In this aspect it is similar to Shakespeare's Merchant of Venice which also has three distinct plots --- the Bond story, the caskets story, and the Lorenzo-Jessica love- intrigue.
Like Shakespeare, Sheridan has interlaced diverse stories in this play in such a manner as to produce an amalgamated impression. The only difference is that, in this play, each plot can exist autonomous of the other but in The Merchant of Venice, all the plots are so thoroughly interwoven that one cannot exist heedlessly of the other.
So, we realize that in a romantic comedy like The Merchant of Venice even comic scenes can be intermingled with grim ones. In The Merchant of Venice, we have the episode of the rings, and the irony of the disguise of Portia as a lawyer. And, of course we see in this play, the sparkling wit of Portia contrasted with the sarcastic and malicious wit of Gratiano in the Trial scene.
Shylock too, though on the whole a comic figure, is made to appear somewhat pathetic, even tragic. The Rivals, on the other hand, follows the antique classical rule of excluding the heartrending elements completely from the scope of comedy.
Sheridan’s play is virginally comical with no tragic element in it. It paints a happy-go-lucky society where people have nothing more grave to worry about than flings and triviality. Their intrigues are the most reflective occupations in their lives. The true spirit of comedy, fun and romp, humour and jocularity and even energetic laughter, reign supreme in this play.
The characters are typically comic. Mrs. Malaprop, Bob Acres, Sir Anthony and Sir Lucius are comic in all they say or do. The servants too do not lag behind in providing their part of fun, by aping the manners of their superiors. Sheridan provokes free laughter through the play and even when he hits, he does not hurt.
His dialogue is also vivid and glistening all over and moves with a comfort, evenness and high-spiritedness. That is the very life of the play.
The Rivals is an artificial comedy of manners that represents the fashionable society predominantly the life at Bath. The scene in this comedy is laid in Bath in the atmosphere of artificiality, maneuvering, duelling and elopement with which Sheridan was familiar.
The purpose of Sheridan in picturing the society of Bath was not to deal with it for its own sake or to keep it as a background, but to epitomize it with a slight satire to hit at the social evils. Since, this has led to a somewhat embellished rendering of the vices and follies, the play has come to be known prevalently as a typical artificial comedy of manners.
There are many references to Bath and its society in The Rivals. Topographical allusions have been made in several cases in the play. There is a reference made to the Gyde's Porch, a place in Bath where Fag asks Thomas to meet him in the evening.
Similarly there are also the allusions to the Parade coffee house and the Abbey at Bath, the latter being the only mental asylum in town. Several references are made to the traditions, customs and regulations followed with rigour and duty in Bath.
An example of the same can be seen when Captain Absolute conceals his sword under his great coat as he is proceeding to fight a duel with Sir Lucius for he too is afraid of being rounded up.
The worst flaw in the play is the sentimental element in it. And this error seems unforgiveable since Sheridan was an avowed enemy of romanticism and had ridiculed it always. He probably could not at once rid himself exclusively of the impurity of sentimentality which he attacked.
Consciously, or not, he allowed the Julia-Faulkland underplot to retain in some measure the conventional phrasing of sentimental comedy.
The explanation of this weakness can be that the force of sentimentality in his age was so strong that even Sheridan could not stay away from being influenced. In another way, we can defend Sheridan for this fault by accepting these scenes as sardonic, which is seldom done.
Another fault that mars the play is its ridiculous element. Although the play amuses the audience throughout with its gaiety, fun and humour, the sense of humour seems to be deliberately exaggerated and therefore verging on the farcical. No one can deny that Mrs. Malaprop, Bob Acres, Sir Lucius or even Sir Anthony are such larger-than-life characters that would have done credit to any farcical play.
But as there is something of a farce in every great comedy The Rivals also has something of a farce. The intellectual duel between Sir Anthony and his son render Sir Anthony utterly ridiculous and worthy to be laughed at. The scenes of Bob being excited to fight a duel by Sir Lucius, and the braggart actually showing his cowardice are certainly worthy of a farce.
Mrs. Malaprop too threatens to degenerate into a farcical character in many places without really ever intending to be so. Due to these scenes and similar ones interspersed throughout the play Allardyce Nicoll condemns the play saying "it breathes an atmosphere of farce and although there is something of farce in every great comedy this lower strain tends to weaken the general effect of Sheridan's work."
Certain improbabilities too mar the play to some extent. Sheridan is criticised for benevolently imparting his own capacity for wit to all his characters, may they be high or low.
The servants in the play are shown to hold more waggishness than they are capable of. In Fag and David, apart from wit there certainly are such qualities which show them lagging much behind their masters. Sheridan's depiction of a character like Lydia whose head is turned by indiscriminate reading of romances is yet another unlikely affair.
Enjoyable and most recommended.
