One thing I'm noticing from the Gamespot review (which is one of the few sites where I half-consider to trust reviews) is that there is a clash of tone. It seems part of the game, and also the reviewer, expect a more grounded experience, maybe because it goes well with the grounded, gritty nature of the Mad Max series, but the other part of the game is more arcade. Lots of hits pet peeves can be translated with "this isn't realistic":
-He complains drinking just gives health, instead of being needed to survive in the desert.
-He complains only certain scrap metal can be used in the upgrade system, instead of the normal, everywhere scrap.
-He complains the main character can somehow carry all those huge scraps,
-He complains how you don't die easily while being run over by a car (on foot) while a few punches in the melee combat are enough to beat you down.
I also like my games to tend more to "realistic" styles, but these all are normal gameplay concessions.
I can't be surprised, this is from the creators of JC1 and JC2, very arcade games.
