By no means is The Way Way Back a bad movie. It’s not terribly original, and beyond that, it’s not very distinctive, but it’s OK. However, it may be the worst kind of OK: Some of this stuff is really, really good … and that means, on balance, some is not very good at all. We’ll focus on the good and highly recommend Allison Janney’s performance (at least the first two scenes of it, before she faded into the shrubbery) and everything Sam Rockwell does here. But this beach-bound coming-of-age story is very familiar and it’s not presented in an engaging way. The boy coming of age (Liam James) is probably too introverted to get hold of. And neither of the other principals, Toni Collette and Steve Carell (as great as Rockwell is here, he’s firmly a supporting player), adds enough to the entrée.
