well, saw it last night.
It's a good film
Look, it's not deep, it's not adding a whole lot new to the superhero genre. But it was very entertaining, even with the plot holes (they all know the secret identity of every other hero, and yet they don't worry that some of the kids will grow up to be villains, as they surely will... this doesn't scream "problem" to anyone?).
Anyway, the acting was better than average. Not amazing, but not anything to complain about. The plot is pretty straightforward and predictable, but it doesn't have any pretense at being anything else, and they way the characters are presented are clever. Bruce Campbell losing a girl to Kevin McDonald was an especially hilarious bit. Sets are solid and the ideas are pretty neat.
Now, what I appreciated most (but not my wife, since she didn't watch teen movies like I did... she just liked the movie because it was fun and entertaining and didn't have ANYTHING dirty in it... unless you consider a SPOILER IN THE NEXT PHRASE fourteen year old kissing a girl he thinks is 18 but was made back into a baby when she was around 30 dirty END SPOILER (note, that this was predictable once you started watching the movie anyway, and will not ruin your movie experience). ANyway, I liked it because there's sort of a secondary tribute to 80s teen movies. The jocks v. geeks, with one geek being propelled to the cool crowd for devious reasons ... plus the soundtrack has no less than 4 songs that are covers of songs featured in John Hughes movies, not the least of which is Morrissey's "Please, Please, Please Let Me Get What I Want." Very cool.
Anyway, it comes recommended. It's not groundbreaking, but it definitely does not suck.
