This movie is a solid 4. Well, really it's more a 3.5 but it gets a half star just for not being another remake.
For me personally the real loss of a star was the character writing. I just didn't care about them at all. Like none of them. The monsters could have won and eaten everyone and I wouldn't have flinch. Might even have cheered.
I didn't hate them I just didn't care about them, but the action, directing, acting, costume, set design, and cool action was entertaining.
Though be warned if you are an over analyzer like me the lack of logic behind some action choice (Made just to look cool but sure ineffective) might bug you but not too bad.
