Old games: Monster sits in the middle the area, doing random attacks and roaring at the camera for no reason. (not many of them had any, well..."realism". Like Gobul, he just sucked in an Epioth or whatever those things were called and bit them once, sat there...and went "boo!" for no reason.

MH4/4U: Your own character is part of the cutscene, like with F. Tigrex...eating some dead monster while your hunter gets a closer look, steps on a twig, and Tigrex immediately catches you and rushes at you at full speed.

Old cutscenes were just random and boring, and basically the monster just showed off for a few seconds.
