Meh, lame, mediocre, shit, terrible etc. aren't really great descriptors for expressing what you don't like about the individual elements of the game though. They're just different words for bad, and you can't tear something down eloquently or--and this is more important--constructively using "bad" alone.
And for people who do like those elements, it's just not very enlightening.
The reviews do a very good job of breaking down why they don't like the game. Again it's fine if you're a fan, but it was pretty clear for a while now this game was destined for mediocrity. The beta was a nightmare.
