I ordered Garden State a few weeks ago and just finished watching it... and I'm a little disappointed. It wasn't at all what I was expecting. I had heard that it was funny, and it was listed as Drama / Comedy / Romance on IMDB. I'd take "Comedy" off that list; it started out mildly funny, but that didn't last for too long. It was a fairly interesting story, and it was touching, but not at all what I was in the mood for. I was hoping for something quirky and hilarious like Scrubs, and what I got was something that was sad and cute instead. It seems like it would be a very good date movie. Of course, I watched it alone in my apartment on a Saturday while doing laundry, and I don't have actual experience from which to conclude that it is a good date movie, but that's still the impression I got.
The best moment in the movie happened early on when Natalie Portman's character uses "lipstick" to decribe... something. I don't want to ruin it for you. Hilarious, though.
The soundtrack was kind of entertaining. I already own a third of the tracks, even including the weirdest one, the Iron and Wine cover of The Postal Service's Such Great Heights.
Anyway, final verdict: don't think that you'll like it just because you're a Scrubs fan. Watch it when you need a chick flick for your significant other... it's not really a chick flick, but it could probably pass for one, and you could do much worse. At least it doesn't have Hugh Grant in it. Don't rent it to laugh or to watch by yourself.
