First up, i watched this movie objectively without refering to the anime/manga content; I expected a well made movie with SnK lore.
What did I get?
Terrible acting, plot holes, atrocious CGI titans and bad sound design.
I feel bad for the actors, because they seem to be trying hard, but are totally out of place in every scene due to their terrible acting (led by the production studio).

I'll go so far to say, that I'll voluntarily pass on Part 2 next month, since I doubt this movie will take a u-turn in every aspect I mentioned above.
2/10 never again

**SPOILER(?)**
At the beginning this scene happened:
*Armin's dad gets eaten by titans*
Eren: "Oh, that's Armin's dad"

Whoever wrote this deserves unlimited amounts of oscars.

I had to force my way through this movie... Sure the CG is awesome and all... But thats about IT!

It was bad. Not gonna lie to you, I expected more. A lot of the plot is changed, a lot is omitted, some characters from manga/anime don't appear at all, like Ervin, or Levi (though there is a guy who's supposed to be Levi, I think, only his name is different). And I think they switched Eren's and Mikasa's personalities, coz in the anime Mikasa is the grumpy one and Eren is the cheerful one, while in the movie it's the other way around. Armin seems lost as usual. I missed seeing the Armored titan here. And some scenes, like the (near) sex scene, made me so confused and uncomfortable that I cringed. The CGI is as good as it gets, the titans are shown as somewhat deformed, but still human-like.
Ended on a cliffhanger (though from manga/anime I know what happens next).
Overall, I'd rate it 3/10. That being said, I can't wait for the next part to come out. Hopefully it's a bit better.

Awful movie. The acting is mediocre and the script is atrocious. The effects looks OK sometimes but other times it was like watching a 90s b movie. And some scenes were so poorly directed that I almost laughed out loud. The anime "touch" it has going only makes things worse. Worst of all must be the characters. Everyone manages to be both bland and annoying at the same time. By far the worst live action movie I've seen so far.

It’s your guys own fault for watching this and expecting anything other than trash, watch the anime it’s amazing

Forget these people, this was amazing

I watch this movie thinking is a anime live action but they change the history... disaponted...
