I recently saw this film called the Lather Effect and I fell in love with it. Its about a bunch of 30 somethings who reunite for a party and in its aftermath talk about old freindships, relationships, and feelings. Its a great character study with great characters. I especially like that they are wearing retro clothes the entire time. Eric Stoltz character is awesome as the 30 yr old stoner who never grew up. I could find a clip that does the film justice but I found this one on youtube:
