It was... Solid.
It wasn't a revelatory experience, and some of it even felt a bit trite. Helmut Bakaitis might as well have been cast to play Wilford. The ending wasn't as smart or innovative as a lot of people are making it out to be, and spare me any "I didn't get it" comments. I got it.
That said, it's slick, stylish, and well-directed. I appreciated the exposition (or lack thereof). The action scenes were cool and memorable. The ensemble was great. Swinton was a standout. Evans was rock-solid.
It's a solid B for me right now. I enjoyed it, but it's definitely behind Apes as far as 2014 sci-fi goes.
