In the last two days, since borrowing Camp from a friend, I have watched the movie in its entirety twice, watched most of the movie twice, and watched miscellaneous other scenes (mostly the musical numbers) several times. Admittedly, this movie is not the pinnacle of movie-making, but it is a fun ride.
I've seen much debate about whether the characters are 'true to life' vs. 'weak stereotypes', and I would argue that in a lot of ways, they're both. The writing is rather sporadic in quality; at times, it is very, very good, at other, very, very bad. (I love the Cinderella line.) The musical numbers are amazing, with favorites of mine being Turkey Lurkey, The Ladies Who Lunch, and Century Plant. The acting varies from character to character; Ellen and Michael I found very well cast in their roles, while it seemed that Vlad was cast for the pretty face, prettier body, and decent voice (and OMG when he sang Wild Horses.....). Vlad (Daniel Letterle) does a decent job with what he's given (which isn't much in some cases), but he's outshone by most of the other cast in all manners except physical form.
For all its flaws, this is an immensely enjoyable movie. This is probably mostly for the musical numbers, but other parts were enjoyable, too. I would recommend renting or borrowing this movie before buying it, however, because it is probably immensely subjective (as evidenced by the polar extremes of most of the reviews). See if you like it before spending the money on it.
