Anne wrote Marcus has an IMAX, but have they been doing much with that lately? I can't even think of the last time I heard of a movie coming out specifically for IMAX theaters.
Marcus (at Crosswoods at least) no longer has an IMAX -- they took out the IMAX sound system and IMAX projection equipment and converted that theater into the "Ultra Screen", which is just another regular movie screen, only really, really big, with more uncomfortable seats than your regular theater, and seating that at least feels much closer to the screen.
My wife and I checked out the new Rave theater this weekend as well, and had pretty much the same perceptions otherwise -- just another theater, nothing that spectacular. I actually thought it was a bit TOO gaudy and neon-y in the entrance/lobby - it looks cool from outside, but inside is way overdone. It reminds me a lot of a Cinemark theater - Marcus and AMC theaters both seem a lot "nicer" - even the simple small detail of carpet in the lobby helps those pass Rave.
The theaters themselves were nice - on par with AMC or Marcus.
As for the movie start-time, I wasn't paying super-close attention to my watch, but I do think the previews started early -- and there WASN'T a slew of non-movie preview ads preceeding them either. Points for that.
