I thought it was very mediocre.
Ok, I know, its fiction, but fuck the title.
Anyway, the movie was like a badly made collage of many other war/adventure epic predecessors. It really had no sense of itself, so it took from just so many other sources, where in those cases sometimes they worked, and didn't in others, and just became a diluted piece of shit. CGI was good, but... so?
The scripting was bad. Like... give us some fucking foundation before you throw out all this generic love bull shit. All the moments where you were supposed to be like "oh, thats why" were so blatant it was just meh. There seemed to be a big chance of bile reaching my mouth on a couple of occasions. Seriously, people just need to strip this formulaic scripting for epics or something and just make it better, because its so bland.
I know there is some element of artistic initiative, as well as a fictitious vision of something prehistorical... but... give me a break.
Sorry, I'm not really sure how to bundle it all up nor really get at the details that bugged me. But the movie isn't good, and I didn't even pay to see it! Man, I would have been pissed to spend ~$10.
