Mini-Review: As usual with Cameron, there are some hints of some interesting ideas, but they are executed somewhat leadenly and not all implications are explored. For an idea movie, this is ... crippling. The effects are fantastic, if you aren't feeling the Uncanny Valley, but the story is somewhat by the numbers. Naturally, it all comes down to the protagonist making A Choice about Who He Is, and that alone seems to make all else possible. Contextually, character and cultural implications are seemingly nil.
Mini-Review: Passable family comedy, with predictable (if well-executed) set-pieces relating to RV travel, that is inexplicably a Robin Williams vehicle (instead of, say, Norm MacDonald). A few verbal solos by Williams aside, most of the comedy is pretty broad and bland.
