Here are my thoughts:
First, and I know this would be a huge (costly) undertaking, but I don't know why TTA still uses tracks. It would be very cool (i.e., "futuristic) for them to use the same technology as they do in Great Movie Ride, U of Energy, etc., to move the cars along. The tracks are loud, clunky, and out of date.
Secondly, with regard to the narration, it's inconsistent -- it's like the attraction doesn't know "what it wants to be when it grows up". In one sense it is a simple "land" narration. Yet, they felt the need to add character voices, so there is some "schmaltz" thrown in there, too. Also, when you get in to SM, you hear a woman who is saying "Pardon our dust..." and goes on to say something about SM being your transportation, blah blah blah, so it is kind of keeping the whole "port" or "futuristic transport" theme from 1994. Oh, and like others have said, the guy's voice is too boring.
Finally, as someone pointed out, I agree that TL has turned in to a "Disney Cartoon-Promoting" land and not the "future that never was" idea (which, in theory, is a good idea). You've got Monsters, Inc., Lilo & Stitch, Toy Story, and even Little Einsteins getting promoted ("Rocket" is on top of the DVC kiosk). Hey, I half expected the Tomorrowland Speedway to change to a Cars theme and call it a day! True, I get it, most of Disney's attractions do just that (i.e., Snow White, Alice's Teacups, etc.), but this, to me, is more in your face.
Again, just my 2-cents.
