incredibly unvaried enemies, essentially 2 aliens you fight no real variety in how you fight. Sure you can stealth, but running of of juice, hiding, recharging over and over is just boring AT the end of the day theres no where difficult enough that you can't just full on assualt anyway so everything else seems pointless. yes buildings blow up pretty if you stop playing the game and start destroying a building, again, its a side thing that has no bearing on the actual gameplay. I think theres really only 1 or maybe 2 instances in the whole game where you can kill 1-2 people inside a shack by smashing it.
The story, is horrible, cliched, finishes as a horrible point and was just so boring. For me it felt like a very pretty engine, coupled with gimmicky gameplay same as Bioshock, where realistically theres no point in stealth, strength or speed, like there was zero need for any of the plasmids bar 1 or 2 in bioshock. New parts of gameplay need to be usable, fast and quick and EFFECTIVE to actually IMPROVE gameplay, most of the new idea's in these games just end up gimmicky, ackward to use and aren't any better than the default option which makes them worthless.
Could have been good with a well writen storyline and something original happening but alas, nothing did.
