Let's knock out some movies, shall we? Here's two to start.
Kick-Ass looks like a comedy starring the extemely funny Chistopher Mintze-Plasse, of Superbad and Role Models. Sorry to disappoint- CMP is NOT the main character, and the comedy found in this is incidental to the action/drama and very, very dark. ("La, la, la, lala-la, la!" sings the high-pitched background singer as the cute little girl in the purple wig cuts down a roomful of unsavory characters with a spear and takes their cash.) Nick Cage's acting-challenged self is also in this, which is okay if you like Tarantino-like bloodshed and laughing at misery. 2.5/5 stars.
Zombieland looks like a light-hearted romp about zombies, and that's what it is. If you're okay with some language and a lot of movie bloodshed, you'll probably love this movie. 3.5/5 stars.
