Don't get me wrong. The GMR in concept is something great. However, as it is now, the GMR is a dinosaur that pales in comparision to almost everything else on hand in Disney Studios--except for maybe the Back Lot Tour which is truly sucky.
Since the GMR and BLT (as well as Star Tours) are the so-called "movie" attractions, then it's high time someone reinvent them into something of higher quality.
True, a few of the audio anamatronics w/in GMR are cool and first rate. I particularly like the end Wizard of Oz scene. But overall, most of it is about as effective as a walk thru a good wax museum.
Now a ride that actually attempts to immerse you in the midst of some of Hollywood's greatest scenes would be cool. Lame as it's become, Star Tours does that. So do so many of the rides at Universal, like Men in Black and Back To the Future.
I'm for the potential of this rumored make-over.
Disney Studios is going to be needing something new soon as it is since all the other parks seem to be getting all the new attractions--otherwise the park will end up being nothing more than a half-day tour for most repeat guests.
And again, I like the overal concept of what the GMR is attempting to be. 12 years ago, this was as good as an attempt as anyone could make. However, A LOT of technology has changed over the years that could and should be utilized to re-do this ride into something as great, innovative, and popular as the Tower of Terror and Rock 'n' Roller Coaster.
