You and I agree. I loved H4. Don't know why it gets the hate. And one of the best looking games of that entire generation.
I feel a lot liked it upto the promethean's so I think the negatives I wouldn't call it hate, started with the promethean levels and lack of diversity now some like those levels but it turned out that a lot didn't at least halo 5 was consistent that was disliked from the beginning.
