Just watched avatar.
Kept an open mind etc. Got into it.
To about half of the film I somehow loved it, I enjoyed the filming and CGI. I loved the idea and the story. I got completely into it until it went downhill, badly:
Couple of wtf moments like a guy completely forgetting his real life, it's not his body he's controlling, how can you throw away like, idk, 30 years of living, after 3 months ? I know you can fly and stuff and walk again but WTF, you're still a human...
The first major wtf moment is when the ( alien) girl of jake sully started to like him, the whole eye contact scenes before were already ''ah god damn it, I knew it'' and finally mating was already wtf. Of course they were destined to fall in love from first sight

.
The 2nd wtf, Michelle Rodriguez turning back and saying ''I didn't sign up for this ****'', of course it had to be her turning back

.
Then the big yellow/red dragon and the population suddenly trusting him for it.
After that the movie got sillier and sillier to cartoon levels of stupidity.
When the end battle starts after a couple of mins in ( when michelle rodrigez shoots the big airship thing of the colonel), I stopped watching, I couldn't watch it anymore, I tried skipping the annoying bits, but the ending really annoys me too much, so dumb...
Overall 4/10, the ending ruins it. 2/10 for the 2nd half of the movie ( aside from a couple of nice shots, this actually winds me up and annoy me rather than entertaining me), 9/10 for the first half. I feel I have underrated the film but I can't deny that I can't even finish watching it, because I got so annoyed from the 2nd half of the film, such a shame, could have been so much better.
