This show is so good, and heart warming, it's not perfect, and of course is for kids, but man, if you like mecha anime give this a chance, is on Bandai Spirits channel on Youtube fully subbed in english and for free, so support them for publishing this for free worldwide!
There's not much to say, this is a plain charming mecha anime for kids, it has some great animation segments, the characters are fun, the story is simple but okay and overall is a fun experience.
So yeah, if you're a fan of overly emotional kids with giant robots, go watch this show!
