Scripts, almost by definition, are not the finished article. Reading 'Romeo and Juliet' is not the same as watching the play although, in that particular case, tedium is always the end result*.
So when I read scripts for something I generally like as much as 'Father Ted' the text seem to float off the page and superimpose themselves over the same events as seen on TV. Which means of course it's almost impossible to write an unbiased review of the words alone.
As always with a collection like this, they are of variable quality, ranging from the sublime ('Hell' depicting the most awful caravan holiday in history) to desperate ('The Mainland' where an ill advised Richard Wilson wanders into a cave to say "I don't believe it.")
If you like watching box sets in a day long binge, then by all means read these scripts one after the other. It doesn't work for me. After a while the events become less surreal and running gags loose their freshness. Mrs Doyle insisting someone has a cup of tea only works the third time if in between you've had a break from Craggy Island.
But then, but then, when it works, oh boy, does it work! Dougal being thicker than thick. Ted with his veneer of normality hiding ... what? I really don't know. Jack and Mrs Doyle as grotesques. All living on another planet and subjected to events of no rhyme or reason but joined in a joyous plot.
I love programs/films/whatever where it is clear everyone concerned is enjoying themselves without getting self-indulgent, and this is one such.
Go read. Go enjoy.
