Enjoyed it overall. It's wildly uneven but its hits are bang-on. Likeable characters and performances from those playing them (and Beansie from The Sopranos!).
Having recently watched David Mercer and Ken Loach's In Two Minds (1967) and Family Life (1971), both of which look at the social and familial roots/consequences of mental illness, I found Silver Linings Playbook a bit superficial and, at times, problematic. Think I might just prefer Loach's more 'respectful' approach, of allowing his actors the visual/physical space in which to (inter)act and embody their characters, rather than heightening and/or stifling the mood and 'subjectivizing' things by upping the aesthetic, intruding upon actors' spaces, etc.
I got swept along happily for the most part, though, including that Lost In Translation-like inaudible whisper, and it's a good job, as upon reflection I realised that the whole mental illness thing's just a Maguffin that's all but forgotten about after the hour mark.
One of those films that wraps up just at the point at which the 'real' drama would begin?
