I like the characters very much. They are all intelligent and rarely do anything stupid that makes you groan. Some characters who would have been turned into a second rate villain in past Godzilla stories are actually very nuanced and have reasonable points of view to do what they think is the right thing. The MC's are not superheroes, but just very intelligent characters trying to do their best, as in real life.
The anime style is very original. It tries its best to balance between cute and realistic. I think they did a pretty good job.
The story is a very interesting original tale, if not a little convoluted. Time travel stories are notoriously hard to keep a track of, and this one is no different. The first half gives you the mystery and is straightforward enough, but the second half gets boggled down by the pseudo-science and at certain points become almost incomprehensible without the MCs giving us an info dump in the way of SMS text messages between the two. Not exactly subtle. Also, let me warn you that the ending is rather abrupt. Not bad, but also not the best.
The best thing about this show is that you can tell the creators love the Godzilla (and other Toho monster) franchises. The EP is simply a love letter to all past films and is an absolute joy to try to find every little bit of Easter Egg in it. I've noticed about two dozen immediately, but my understanding is that there are a heck of a lot more.
I would absolutely recommend this show. It is fun. It is certainly much better than the last attempt to animate Godzilla.
