Halo 2 and 3 are my favorite Halos. Hate Halo 1 due to repetitiveness. Halo Reach is okay to me, I really enjoyed the multiplayer but the campaign was kinda a chore with the receptiveness like Halo 1 but not that bad.
Halo 4 has to be the worst with the most boring campaign that is a chore to play through and the most lackluster multiplayer.

instead of innovating a field they heavily influenced, they're copying games like COD.
and the series is going downhill 
Halo 5 was the least sold Halo game, that should tell you everything. Halo 5 global sales were around 3 million (as of feb) and Halo 3 was over 12 million.
(before some clown negs me yes I'm joking)
the game is dying because of 343.
