Oh men, this was disappointing. The only character I cared about dies in the first episode.
After watching the 2nd episode I knew this was a completely waste of time, but we continued because my girlfriend has more expectations on it. Finally, she desisted at 7th, and we finished it just because I didn't want to have it on Trakt's dashboard.
The good (unexplored) things: The Aliens are a new thing, this design of life form (or are they bots? We have to wait until 2nd season, if there's any) is the most interesting thing in the show.
The bad? I think the writing and the general rhythm becomes boring (if you're generous)...
There's complete parts we skip to not fell asleep and there's some actions that feels a little fool of the characters.
Mitsuki is a Mary Sue, she can do anything, fix anything, resolve anything, just because who is she.
Cole (the military one) feels like he's the world's chief just because he's American. The attitude of "Hey I'm an American soldier, let me in, let me pass, there's nothing prohibited to me, there's no place I respect" is really annoying. Nothing else to say that he apparently doesn't have to eat or even drink water, and had the power to make international calls during a world crisis from a public phone.
Caspar and Yamila becomes the most interesting characters, even when we don't have some explanation about how and why Caspar had the ability to "see" the alien's minds...
Oh! And there's the thing about the "darkness" in the show. I dont know how can explain if having all the technology available for content creating the producers decided to make this show so dark. There's scenes more undistinguishable than "The Dark Night" on Game of Thrones, or the dark scenes of House of the Dragon. And the worst part is that they are not even at night!
Conclusion: there's more interesting ways you can spend your free time.
