First, I'd like to say I really enjoyed *most* of the special effects. There were moments where the CGI was worse than pre-2000 CGI, although to be fair, it was mostly in the background but they were awful. As an example, pay attention to the armies fighting in the beginning.
Second, the acting for the most part wasn't too bad.
Here's what bothers me and I haven't seen any reviewers address these. If you have to read the subtitles, you spent some time thinking "What??" due to their translations. It feels like they ran some of it through Google Translate. Some of it was good, while some sounded like they were purposefully trying to make it sound like broken English. Then there was the out of place use of modern English slang like "small potatoes" or the informal "wanna" in addition to other parts that just sounded downright childish. Did the person or people who did the English subtitle translations not speak English very well? I can't understand why you wouldn't at the very least pay some American college kids $100 a piece to proof read it. It wouldn't be that hard. I mean, the internet, right?! I'm pretty sure that given a few hours time, I could make the English translation sound 1000% better, while keeping to the spirit of the movie.
Then there is the portrayal of the Monkey King. For the most part it was pretty good but all the blinking and there was LOTS of blinking. So much so that it would have given an epileptic a seizure. Did he think monkeys have really bad eyes? Add the stupid surprised faces that got on my nerves and it gets really old. It didn't help that he even did the begging dog pose, which I'm SURE isn't actually a thing with monkeys of any type.
All said, it's a decent movie with some redeeming qualities that understandably isn't geared towards an English speaking audience. I just wish if they were going to bother with it, why they couldn't get it right.
