Well this was a fun project. I looked through several lists of what were called 2008 movies (though I notice that IMDb, which I consider the arbiter, didn't always agree, and called some of them 2007, but if they were on a 2008 list, and I felt like including them, here they are).
My Top Movies of 2008:
Walk Hard (Great and respectful parody of Ray, Walk the Line, The Doors, and others. I really enjoy John C. Reilly.)
Synecdoche, New York (Oh man, someone see it!)
Rachel Getting Married (Our Ann, and my Bill Irwin and Anna Deveare Smith AND it's set in a wonderful Connecticut house)
You Don't Mess with the Zohan (I have a weakness for the more mature Adam Sandler, alright?)
Miss Pettigrew Lives for a Day (Frances McDormand steps in lucky shit.)
Movies I enjoyed, but wouldn't call top:
Get Smart (I also have a fondness for Steve Carell, and in fact had an erotic dream about him recently.)
Baby Mama (Especially liked Amy Poehler. Tina Fey's character was a little too annoying.)
Hancock (I also have a fondness for Jason Bateman. Hey, you're learning all kinds of personal things about me.)
Bottom:
The Dark Knight (Don't hate me. I never would have seen it if it weren't for you know.)
Burn After Reading (Liked the first four fifths quite a lot, but was so annoyed by the last fifth, that it puts it on this list.)
Sex and the City (All the predictable fatuous vapidity of the TV show, with none of the wit or insightful social commentary or true pathos. And I saw every episode of all six seasons, so I feel confident of what I'm saying. Why did they think we'd care more about the size and contents of Carrie's closet than about how their actual lives were going? And the big joke of the movie was Samantha actually has diarrhea on a fabulous tropical vacation, while we and the other three "girls" watch. Um, hunh?)
Vantage Point (Great premise, could have used better writers to actually tighten up the weak plot points.)
Horton Hears a Who! (Insulted homeschoolers, of which I am one. I have to admit I fell asleep during it, so did miss a good bit.)
Ones I still want to see, roughly in order of desire:
Frost/Nixon (I admire Ron Howard.)
Milk (Because it's Harvey Milk, and Sean Penn playing him with love.)
The Women (I LOVED the Clare Booth Luce original. And it has Carrie Fisher and Cloris Leachman, two of the smartest.)
Wendy and Lucy (You know why. Plus it's in my beautiful southern neighbor, Oregon.)
The Curious Case of Benjamin Button (Sounds intriguing, and I want to hear Brad Pitt's accent.)
CSNY (I have Crosby, Stills, Nash and Young in my cells.)
Trumbo (About Dalton Trumbo, blacklisted writer of "Johnny Got His Gun," and other powerful stories.)
Chicago 10 (Should make this a double feature with CSNY.)
Pineapple Express (Judd Apatow and Seth Rogen.)
Zack and Miri Make a Porno (What can I say?)
Step Brothers (More what can I say?)
Battle in Seattle (The revolution will be movie-ized.)
The Business of Being Born (Because I'm a proponent of respectful birth.)
The Secret Life of Bees (I think I read the book and liked it.)
Then She Found Me (Did read the book and liked it a lot. Also Helen Hunt's directing debut.)
Humboldt County (For someone who hasn't smoked marijuana since 1987, I sure enjoy it in movies sometimes.)
Tropic Thunder (I dunno.)
In Bruges (I hear it's good.)
Where the Wild Things Are (Michelle Williams and Maurice Sendak. Though can it compare to the Carole King version?)
Be Kind Rewind (Okay, I like Jack Black too. Now you know how unbelievably low brow I am.)
