There are some intense and somewhat "uncomfortable" moments but, to me, they were believable and gave the film some depth. I loved the way the characters dropped their facades in the final scenes - now that's a real "truth-telling circle".
The juxtaposition of different cultures and personalities was written brilliantly. I expect that sociologists will have a blast with this film.
I rented this, despite the low rating, because of Jennifer Aniston and Paul Rudd whom I consider to be wonderful comedic actors. It's great to see them together again.
