The negativity has come from its long development time. While the game still promises a lot and looks like it will continue to build to something great. It has taken its time getting to where it is now.
As whether the game will be as good as it's supposed to be is all dependent on time. While you can play the game now and have fun with it, it's nowhere near to how good it is supposed to be. That all due to the fact the game is still in heavy development due to Chris Roberts Epic scope for the game.
I still believe the game will be as good as it's supposed to be but it will just take its time to get there.
