Our Idiot Brother (2011)

Rudd is sweet as the titular brother whose honesty and good-samaritan tendencies land him in jail and then into the homes of his mother and sisters.  He then proceeds to mess up their well-ordered lives with his complete lack of guile.

This is one of those "the screw-up is the only one who actually has his life together" stories.  Of course, I say that and then can't think of a single example of a prior movie that falls in that category -- but I'm sure there is one since it felt like I'd seen this before.

Likable but obvious.
