It's no Notting Hill, but has some of that romcom feeling. Is based on a real dude named Henry "Harry" Hallowes (with the romcom bit added in, presumably to detract from the hermit storyline).
Diane Keaton—as always—manages to play herself, dress as she always does, and pretty much get away with it.
If you like her floppy, daffy, arms akimbo flirtiness (as displayed in most every movie she takes on), you'll like her here. If you don't, well, sit this one out because it's more of the same.
