...and on ZMF's "Optional/Not Optional" scale:
9 Songs: Not a movie, more like pornography spliced with concert footage. Optional.
30 Rock season 3: Just about as good as the first two seasons. Not optional.
Adventureland: It's about a socially inept writing major and the emotionally destructive girl who makes or breaks him-- yeah, this one hit really, really close to home, but it was damn good. Not optional.
Andy Richter Controls the Universe: As funny as I remember it being-- maybe funnier. Not optional.
Barton Fink: Falls somewhere in the middle of the Great Coens Ratings List. Optional.
Black Sheep: You'd think a movie about man-eating sheep that turn people into were-sheep would be, you know, better. Optional.
Brick: A cool high school film noir with dialogue and atmosphere that takes a bit of getting used to; worth it. Not optional.
Californication season 2: The definition of guilty pleasure. Optional, for that reason, but I like it.
Celebrity: Kenneth Branagh tries his best Woody Allen impression in a Woody Allen movie, Woody Allen Woody Allen. Optional.
Cowboy Bebop: The Movie: Like a really good episode of the show, but not as great as the show itself. Optional, I guess? Make up your own damn mind.
Crank 2: High Voltage: The batshittest movie ever put to celluloid, and one of my favorite films of the year. Not optional.
Dexter season 3: Not as good as the first two, by a lot. Optional.
Drag Me to Hell: Middlin' Sam Raimi, not a patch on Evil Dead 2. Optional.
Good Night, and Good Luck: A great portrayal of the social responsibility of journalism, which is just what we need right now. Not optional.
Gran Torino: Clint Eastwood at his scowliest, in a movie that could be about my dad. Optional, though.
I Love You, Man: Way funnier than I thought it'd be, Bro Montana. Not optional if you like humorous things and/or Lou Ferrigno.
IT Crowd season 3: Very nearly a funny sitcom. Optional.
Once: The songs are great, but everything else is sort of there. Optional. Soundtrack? Not optional.
Primer: This must be how people who hate time travel stories feel all the time; this movie is smarter than me. Not optional.
The Royal Tenenbaums: Wes Anderson makes films like Kurt Vonnegut writes books (don't ask me to explain that; I can't). Not optional.
Star Trek (2009): All spectacle, no substance; too much Lucas, not enough Roddenberry. Optional.
Stupid Teenagers Must Die!: Stupid, should die. Optional.
Visioneers: Galifianakis can do better, and has; dull to the point of annoyance and forgettable. Optional.
Watchmen: Sort of like Watchmen, only with more fight scenes, violence, sex, cursing, and slow motion; read the book, for Chrissakes. Optional.
Zombieland: (That's right, I went to a theater!) It's no Shaun of the Dead, but it's better than 98% of those other tired, dead-eyed zombie pictures. Not optional if your taste is remotely similar to mine.
