The whole DLC was underwhelming; it was a three phase rogue-like, where shit from Kratos's mind manifests, and at the end he eventually forgives himself while he monologues at his younger self sitting on Ares's Throne. I managed the whole thing (and trophies) within about 7 hours, and part of that was just figuring shit out, powering up, and a bit of de-rusting.
The last Marvel game I remember playing was the... 2013ish Deadpool game. The people who made that game at least captured the spirit of who Deadpool is and going with the weird obnoxious shit he does. I remember Mr. Sinister being in that game, but not even as a boss fight, and he looked, like his old style, IIRC.
