Yes...and an element that was frequently missing from Star Trek later as well.
Voyager had a fair bit of fun and adventurous spirit. It did comedies the best of any Trek series IMO. However, it was criticised for its lack of things like internal conflict and a more desperate situation for the ship - ie. for not being dark enough. Enterprise, of course, wound up taking that darker path in season 3 - and was criticised for being too grim.
The lesson being that you'll never please all fans.
This and other interviews from Rainn Wilson makes it seem, like DIS Mudd will be a completely different character than TOS Mudd. Not even a hint of a comic relief. Just a typical nasty criminal.
I don't know about that; in retrospect his actions in Mudd's Women were pretty nasty (in fact the whole episode is really dark). I don't see it as much of a stretch for him to be a potentially nasty and dangerous character in a certain situation.
