Jessica Jones is the only one of the Netflix series I truly enjoyed, although the first series of Daredevil was pretty good. On the whole the more gratuitous violence side of it all doesn't particularly appeal to me, though. And I really can't deal with mopey superheroes. Pathos is good, shocking moments are good, but they're things I think need to happen in very small doses for them to really work in this context.
Having not read said comics, I can't comment much other than what you're saying does sound tedious. One thing about the films is, because they are comparatively few and far between for each character, they can't spend too much time being self-indulgent with the characters' darker sides, because they've only got two hours to endanger the world, save it, and make a thousand Joss Whedon-style jokes along the way. The fact that most of these new Disney+ series seem to be tied much closer to the films than most of the previous series does mean there's more scope to potentially do 'aftermath of being film events' type stories which aren't necessarily what I'd want to watch (the low point of Agents of S.H.I.E.L.D. for me was the immediate aftermath of Winter Soldier - watching the characters just be sad / angry about Hydra week after week got dull), but I'm hoping this isn't the case.
