Venom, Magneto, Loki, Emma frost too many great marvel villains ruined by turning them into heroes because they are popular
I definitely agree with this. I'd rather have a more interesting, compelling, and "complete" villain than one who flip flops. I do have a soft spot for slightly maniacal, but mostly passionate villains, though, but they come off as rather flat and as not having any staying power.
This was worth watching just to see G-Man dance. While I do like the idea of villains getting their own series, I just hope they can keep them interesting, engaging, and try to have them come across in a fresh-ish way. I know I'm asking too much but I was immediately taken by Magneto when I first saw him and think he needs a good writer to not only further develop and push his powers, but to also take his personality in a new direction.
