Apparently a lot of contemporary peeps thought the fourth act was dull, I honestly found it the best part. Antony was pretty insufferable, as was Adele, but I've come to expect that from Romantic fiction. I was a fan of the vicomtesse, and even though there wasn't too much action, I never found any of the parts slow... perhaps a little heavy on exposition but overall entertaining, and if you are not a native french speaker, a fairly accessible reading level. Just don't read the preface of the folio edition, it was incredibly dull and spoilery and just really not enjoyable, or even particularly additive to my reading experience.
