I thought that it was a fun, but very inconsistent show.
When it was doing something, it was really enjoyable. When it wasn't, it was really dull. I'd say that the show was 50/50 for both.
One of my biggest criticisms though, is that there were a lot of characters who have (so far) been entirely irrelevant. Like the new Guardians of the Globe, for example. It is entirely possible that they have a much bigger role in Season 2 and beyond, but solely in the context of this season, if none of the characters in the new team existed in the show, the show's overall plot would not change one bit. What this meant is that there were multiple scenes focusing on characters who just... didn't really have much to do, in the grand scheme of things, and that time could have been better spent further developing the main cast.
I'd say it was a 5/10. Im still excited to see where the show goes, because I really like the plotline that they have established, but the show really needs to work out a lot of flaws before I can consider it to be "good".
