Of course it has more potential, but I challenge you to find any attraction that cannot be perfected.
It is what it is, and barring another 6 month closure real soon, the track and descent will not change dramatically, and I'm okay with that. It's not the end of the world for me and it most definitley isn't SGE, JIYIWF, or Tiki Room UNM. The majority of the ride is absolutely wonderful, and the ending is good enough for me and most of the people I've overheard...I don't make this stuff up.
The EPCOT that I know is about optimism towards the future, not being afraid of change, and if you can dream it, you can do it...that's also what I try to model my life after. Over the past few days, I have read nothing but negativity, pessimism, you name it from EPCOT "fans". This may not be the ideal SSE refurb that you envisioned, but it's what Imagineering, Siemens, and Disney did envision. Sure it's not perfect, nothing on Earth is, but you can make the most out of what you have. The first 2/3 of the attraction are spot-on amazing...after that, go ahead and take your nap, spend "quality time" with someone you love, or lord forbid, actually try to enjoy the touchscreen in front of you for the 5 minutes it takes to get back to Earth and enjoy the pretty music.
This is America, so you are free to judge an attraction from previews and youtube videos, but let's wait till February to damn it/WDI to hell. I truly hope that everything works to perfection when TSM opens next spring when Merf and Co. ride...
SSE is not the worst attraction at WDW, nor is it the best, but it is pretty damn cool. And I feel very fortunate to have had the opportunity to ride it before my experience here ends in January.
Perhaps I'm just weird, but I prefer to look at the bright side of things, especially when experiencing new attractions. I can't imagine how dreadful it must be to go through life looking for things to go wrong.
