Bah, I enjoyed the film thoroughly, as I did the second one. Was sad after the movie ended too... just knowing that this was it. And dropped the ball? What do you expect? Really now... what is it that you wanted to see?
I did read one review before I saw the flick (was in the paper and I couldn't help it >_>) and it was mostly negative. Did I expect to be disappointed? Certainly not! I've grown attached (so to speak) with the characters and was quite excited to see how this third one progressed. Sure, I wish a couple things could have been different, but I didn't write the story. ;D
For the sake of not spoiling the film, I'm not gonna mention anything in detail from the film itself. I will say that the "mech" scene was pretty damn awesome. Other than that, a couple scenes kept me on the edge of my seat as well.
I don't mean to rant... I guess I'm just not the "critic" type. I watch these things to enjoy them, not analyze them. ;p
(not to be taken as a cheapshot!)
Go ahead, brand me as a mainstreamer now. ;D
