It was a very enjoyable movie. It was an action movie based on a silly premise combining many aspects of monster movies and mech related thing. And it delivers! Sure, some of the acting was a bit cheesy, and the story is pretty basic, but that's not why you are watching this movie. I guess it was refreshing for me because it was an original film (though based off of many things like I just said), and a fun summer movie that was lighthearted and beautiful, without using special effects where it feels like the animators were just jingling keys in your face despite the fact that there was a heavy use of them. In this day and age, that's tough to pull off.
