I finished Space Force last night. It wasn't bad. I'm not sure if I "liked" it, but it was definitely OK. It's very watchable and has good production values.
The comedy is amusing, but not laugh out loud funny. Fortunately, there is some drama and character development, too. It reminded me slightly of how The Orville wasn't as funny as I expected, but that wasn't necessarily a bad thing because it had more depth than I expected. I can't compare this to The Office because I've never seen that, but I wonder if people doing exactly that are those most disappointed because they expected it to be as funny as that.
I'm not a Steve Carell fan, but I liked his character as the General in charge of Space Force. He's bumbling, but also sincere. John Malkovich's character, as the head scientist who acts like he's smarter than everyone else, is often annoying, but he has his moments and the contrast between him and Carell's character is good. As someone said earlier in the thread, the daughter character was really annoying because of how toxic her personality is. I hoped that she would undergo some character development and become likable by the end, but she doesn't. I hope that she gets a personality overhaul for next season.
Others will like the show for its political satire, but I wasn't much of a fan of it. Trump is basically a character in the series, even though he's never seen or named. He's just "the POTUS" that the characters are always referencing and whose constant unreasonable demands make the job of Carell's character harder. The First Lady is even interested in fashion. It's sort of funny, but I also like to get away from the real world late at night. There are also lots and lots of jokes made at the military's expense, especially jokes about being overly aggressive and wanting to use bombs to solve everything. It's all in good fun, but just realize that that forms the basis of a lot of the comedy.
Anyways, while I didn't love it, I also don't regret watching it. I'll eventually watch a Season 2, which I can see being better, especially because this season gets a little better as it moves along. This isn't the greatest of starts, but the series has potential. I would recommend it if you keep your expectations low (especially if you don't expect it to be as funny as comedies like The Office or as satirical as shows like Veep).
