Why should the game not be compared to console FPS games? Does the smaller screen limit originality, creativity and level design? This isn't the age of the GBA anymore, Vita games can look damn good (as proven by this game) and there is really nothing holding it back. What I read in reviews was that while this is a good game, its not special or remarkable, its just going through the motions and as such, a 77% is right about where it should be on the current review scale.
Also, user reviews mean nothing. You proved it yourself when you said that that atrocious CoD Vita game got a 4/5 from users.
EDIT: @MikeRox: did you read RE: Revelations reviews? the most common complaints were the controls (single analog) and the fact that the campaign was fragmented (to make it more accessible for handhelds). So yeah, it did get marked down for being on a handheld and for good reason.
I think graphics are the only area in which review scores should be scaled to the console btw
