Rayman Origins was easily one of the most disappointing games of last gen for me, i'll never understand the praise for that scholastic, boring ass, flat level design. Backgrounds art is absolutely amazing, but they ruined the usual Rayman tone, which was always ironic, not dumb. I also found music to be unsufferable, except for a few tracks.
Never bought Legends because of this, although i tried the demo on the Wii U and that musical level with Black Betty was very fun. All in all RO doesn't even compre to the first Rayman, let alone the true benchmarks of the genre like Super Mario Bros. 3, World and DK Tropical Freeze, which are several notches above in level design and gameplay.
