I'm playing through it right now, and I really think this captures my thoughts, too. I do think if you go into it expecting it to be Arkham, you'll be really disappointed because it's obvious they are trying to ape its legacy. It's actually a pretty fun game, not as good as the Arkham games, but it's not shit tier. It's playable, combat can be a lot of fun. My biggest gripe is the loot system, I don't mind collecting things to unlock skins and different skin colors, but I hate unnecessary crafting garbage. Should've just made the unlocks a reward for finding collectibles, but I'm guessing the loot system was a by product of trying to make it a GaaS game, and when they switched it to most singleplayer, they had to leave a lot of that junk in.
FWIW, the game is fixed on PC. I am playing it at 1440pUltra on a 5800X3D with 3080 Ti, getting about 120 fps, dips to the low 80s occasionally but basically silky smooth. Zero shader compilation stutter during cutscenes, a noted issue with the original release on PC.
