This was my favorite ride at MGM on previous trips (yes, even after I rode TOT for the first time, I still loved Movie Ride). This last time, though, it lost something for me. A lot depends on the acting ability of your guide, and we got some real duds. Though that provided a certain amount of amusement in itself.
If the line's not too long (it often is, for us it was often more of a wait than TOT), definitely give it a try- it does have some amazing scenes and music.
