Yes, its a bad thing, I find myself being bored with most things that involve those two.
- He is dumb in Super to the point is not funny, I thought he was playing around in episode 42, but the recent episode tell me otherwise and it surely will continue like that with Goku genuinely thinking Monaka is stronger.
- His only motive in the series is to be stronger, whenever he's on screen it shows he's training, he cant live without fighting or training
- Vegeta has become boring.. First in Battle of Gods we saw he cares about Bulma and the others and that was good, I loved it in the movie, but then in Super, the same thing happened and more, with Beerus being a jerk. Then after that we constantly see how Vegeta protects Bulma from Beerus or Goku and he talks to her as a pairing (Vegeta, the character that didn't like to show he has affection for others).
I mean give me a break, have him not care about anyone for a good time or something and then you can return showing he cares...
thats what made Vegeta fun, he was embarrased the moment the other characters noticed he cared, especialy if the character was Goku.
Also what other people have said, these characters are already developed, specially Vegeta, so whatever happen with them now its not a surprise and theres nothing new.
