Finished JJ2 last night, it was certainly not the best show but I'm not going to go quite so far as to call it a train wreck either. Tellingly by far the best episode was
the one where Killgrave comes back - Tennant plays the role so well. As an episode it actually had the most interesting story playing out as well.
As others have said they do spend quite a lot of time away from Jones this season, but when the central story involving her is really not that interesting I can't imagine I would have wanted to see more of it! The trouble is that where decent B plots can do something to save a weak A plot, they don't manage to deliver on those either!
The stuff with Hogarth was just odd -
it just didn't feel right that she would be taken in by these 2-bit hustlers like she was. Although her manipulation of the girl at the end was a decent resolution. Malcolm and Patsy are also just not very interesting characters at this point - they desperately need to do something to justify the level of attention the show gives them!
All in all I'd give it a 6/10 - not awful but pretty difficult to get through all the same.
On to The Punisher next
Current rankings from me would be:
DD1 > JJ1 > DD2/LC1 < TD < JJ2/IF1
