Having ridden the TTA 6 times in the last two days, I can say I am not thrilled about the new narration, but it's not as terrible as I thought it was the first time I rode. My biggest problem is that there are no standout 'quoteable' lines like with the old version. I think the old version had plenty of gaps, problems, etc., but it was always fun to hear certain parts in various places in Tomorrowland. This new narration is better fleshed out, but it just lacks anything memorable. About the only line I can think of as being potentially quotable (at least the only one that stuck with me) was the bit that the Peoplemover "never stops" near the end of the attraction.
I think the narrator sounds a bit like the narrator on the SSE descent.
By the way, anyone know where I can find some audio files of the "Paging Mr. Tom Morrow" and "Now Approaching" bits? I don't want the entire TTA recording, just those 5-10 second files, if they're available somewhere. I checked Mousebits, but didn't see anything. However, that doesn't mean they're not there, I'm notoriously bad at searching that site. Thanks in advance.
