The combat is kinda barebones but servisable but only when you don't have to deal with the slowmo kicking in every three second just to be super annoying to look at and to mess with your timings to block/dodge at stuff. On a side note, the punches have a very satisfying kick (heh) to them, reminds me of the action scenes in Snyder's movies.
The bosses are also really fucking lame, not a single one is worth remembering, not even the final boss which is by far the worst of the bunch.
The level design is nice and I like that the map is on the smaller end of the spectrum, but the collectibles are mostly on plain sight and there are a fuckton of them.
The story is okay but very simple and straightforward yet it has some cool moments.
The AI is kinda surprising, the guards react to their homies being knocked down in stealth sections and start covering each others backs and being more afraid of you with every elimination, really sells the feeling of being Batman.
Overall a pretty average game with a lot of room of improvement.
