Click-baiting as legit business practice has become the norm of game "journalism", so nothing really surprising there...most gaming sites have gone to shit for quite some time now.

Meh, it's their opinion.

Mine is that Bioshock Infinite is the best video game since Mario Galaxy 2.

It might be overated but 4/10 is a little harsh. I'd give it 6/10

Pretty stupid criticism. At Wounded Knee people were slaughtered more or less indiscriminately. I believe well over a hundred women and children were killed. There is quite a difference between that and the enemies in Bioshock Infinite, who are all adult males, and will all fire at you, and help hold up a corrupt system that abuses those without power, and are trying to imprison a young girl.

The game is not flawless in fact i think it has many flaws but i think its anything but below average 

I think 4 out of 10 is a bit nuts, but I have to admit that I found huge chunks of that to be tiresome and not very fun.  It didn't come anywhere near capturing my imagination like the original Bioshock did.  Heck, I think Bioshock 2 is a better game than Infinite, and that game got tiresome to me too.  

The environment in the original Bioshock was just so magical.  The environments were varied and interesting.  I just didn't get that from Infinite.  Infinite felt the same from start to finish, and I agree as well that the Booker was uninteresting, and I just couldn't be bothered to to care about him.  I thought the end was pretty much dumb.  I thought it was 2001 Space Odyssey (the movie, not the book) levels of incomprehensibility.  

That said, I'd still give it a 7 out of 10.  It was an interesting enough concept, with decent mechanics and environments, but it was average at best overall.

What is the point in reviewing it now? Should I go back in time and not buy it?

Really?  That's not the same game I played.  Your motives in Infinite aren't made clear until the end, and even Booker seems confused about them.  Plus, for most of the game you're just trying to kidnap her for your own reasons, and you aren't a very good guy in the beginning...  Let's not even get started on the ending either.  Booker's just a bad dude, it seems to me.  Past, present, and future(s)...err future past, future present, past present, future.  When is he good except in your own mind when you (the player) are wishing him to be good?  

Obviously the ending of that game left me very cold.  And I'm a HUGE Bioshock 1 fan.  If it's not my game of the gen, it's tied for it.  Infinite doesn't even feel like it was made by the same people who made the first game.

Gamespot has very consistently proven itself to be a sack of dicks.
