For the record, Sideways was an excellent movie...
It was, but not because of Giammati's performance. Now, American Splendor was a movie he carried, I'd grant, but it was also 2003. The guy had two good years where he picked scripts that weren't absolute train wrecks. He's ludicrously overrated because of the "Sideways" buzz. He's a mediocre character actor who's name shouldn't be spoken in the same sentence with actual talented character actors like William H Macy, John Riley, Steve Buscemi, John Tutoro, etc.
There are hundreds of actors better for this role than he, but he had the best name recognition/willing to work for short money combination to get the part.
