The problem is that gamers expect more of game journalists. Bioshock is a fine game, but not a 95% worth masterpiece.
I think most people are frustrated with game journalists simply joining the hypetrain and not doing their job. As a developer, I always try to play games with an open eye and usually can relatively easily spot the flaws of a game - Not that this makes it unenjoyable to play, but then reading that the product has no flaws and is just 5% short of perfect is kinda screwed up.
And this isn't the first time this has been happening:

Remember this? 10/10, perfect game, 'A triumph', they said. I'm pretty sure it's pretty obvious to everyone out there that Skyward Sword was a very good, but also deeply flawed game. You'd probably think of a 8/10 there.
And let's look at a crazier example:

Doom 3. Great looking tech demo, not quite the game anyone was hoping for. Tons of issues and flaws in that one. Look at how many journalists gave the game perfect scores. 94% says PC Gamer.
Assassins Creed 1? Same thing.
Bioshock Infinite is a good game with some really blatant flaws, it's annoying and stupid that game journalists aren't willing to do their job, a job that would help the industry mature and ultimately lead us to make better games. This is also part of the reason why people actually do lose their jobs or studios not able to work on riskier visions. I don't know why it's so bad to have an open, honest, true conversation about a game and look at what it's getting right and what it's getting wrong.
This kind of 'let's hype everything, everything is amazing and we love drinking the kool-aid!' approach to being a critique limits where we could go and ultimately also limits journalists themselves.
