I'm about 3 Symbiote Nests away from %100ing the game, I have my nitpicks, but the game overall is extremely well-done, and I would argue is Insomniac's Arkham City moment in many ways. Didn't really mind the MJ stuff tbh, I am honestly completely done with the entire woke vs antiwoke thing that's happening in media discussions, I thought the MJ sections were more well-done mechanically than SM1, but YMMV on whether a change of pace is needed there or not.
The boss battles have largely been good and extremely engaging in a way (particularly Kraven and Lizard), with that said, I have problems with the final boss fight, mainly that it went on too long. I would rather have one less boss phase in exchange of a more interactive version of whatever happens between those phases.
One thing I really, really liked was how Insomniac chose to conclude the various side quests in the game, the Mysterio boss fight was a highlight of the game, as were the Flame and Chameleon side quests, I feel the latter two are very clearly set-up for a DLC of some sort, which I will likely play from moment 1.
Right now, this and AW2 are my joint game of the year (still to try Star Ocean 2R and some other games tho).
