One thing I've noticed from all the reviews above, is that there is a lot of talk about the technology and CGI, but very little about the actual plot/acting/script etc.
I'm hoping that this movie isnt another Transformers2 - great CGI but such a poor storyline that those who wrote the movie should be jailed.
There is only 1 proper review (Phonesis) and aside from the CGI, visuals and 3d effects, he clearly states that it isn't really a great movie.
Myself, although I love great special FX, as was the case with Transformers2, I value a good storyline more. Perhaps it is my age (35), where flashy graphics no longer take centre stage.
I'll still be watching it, though.
