Is it that bad

I went to go download the game because I remember playing halo 1 and 2 multiplayer for a long time and it was one of the Best shooters next to call of duty. So I was going through the reviews and there's not a single good one I've come across. I'm not sure wether to believe the hate review bombing or what. I'm not trying to wait for the download If it really isn't good. I didn't know they made anything past halo 2 it's been a few years since those 2 came out and I never followed the game close enough to know they released another game
