It's all funny enough but the whole thing didn't quite work for me. I wanted more about their pre-painting friendship in order to make sense of what the underlying issues were. There are hints of that (especially with respect to Yvan) but it isn't really explored.
The three performers were all quite good. Michael Russotto as Yvan was especially memorable in his hysterical monologue about a conflict over wedding invitations.
On a more serious note, I have often wondered about how we develop our tastes and what they say about us. I can't say I've ever noticed any particular correlation between personality and artistic tastes, other than my conviction that anybody over 25 who still thinks the Impressionists are the pinnacle of art is a bit unimaginative. (It is one thing to have a poster of Monet's "Water Lilies" on the wall of a college dorm room. By the time you're an adult, you should have branched out. I wouldn't drop our friendship over this, however.) This applies to other art forms, too. I even have friends who like country music.
