Finally got around to seeing Sideways last night. Overall, I'd give it a B+ -- It certainly wasn't the best movie EVAR the hype made it seem, but it was definitely was enjoyable. At first all the wine talk made me desperate for a bottle (and I do think the film would move up to A-/A territory if I had been drinking along), but eventually the characters go through so much wine in a single night that it actually turned me off the idea of a glass of red.
And for those of you who might think Sideways just looks like a story about two miserable schmucks, the end does have some redemption in it.
I'd recommend Sideways as kind of a double date flick -- get some friends together, crack a bottle of Pinot Noir (or two), and watch the film early so you can keep the conversation and good times rolling afterward.
