Did not care for any of the supporting characters...

Agreed. Col Birch really hammed it to excess. Olivia seemed in her first acting job. The fat guy who wanted to go on a date showed more convincing personality than the others. The shrink with the beard was okay; the other guy talked like a robot.

I actually wish they'd found a better actress for Eleanor; overall, the weak acting was a distraction. But I enjoyed the movie all the same. B-, I'd say.
