Seen it at the time, almost completely forgot it. The main thing I remember is the blue avatars and the trees thing. If it were better, should have remembered more than that (comparing it with other movies). Also, don't feel the urge to rewatch it.

Take out the marketing hype and the special effects, and the story is just a B type Sci Fi, with some sentimental elements included. It really does not feel like "wow, what if this were true... the possibilities...". The mind is resting with this one, and it is not a compliment.
