Actually, no I'm not saying that they all should have a cartoonish type of addition, but, I also don't feel that the addition is something that is sacrilege or a disaster. The concept of no Disney characters in Epcot is bogus to begin with and has been proven over and over, but, still persists. I didn't like what they did with the SSE to accommodate the hand and wand. The stars embedded in the structure was something that made me flinch every time I saw it, but, the idea of having the hand and wand (sans stars on SSE) was for more then one purpose. The common misconception of first time visitors or visitors (Guest) that weren't obsessed like us, felt that Epcot was not part of WDW. The hand and wand connected Epcot with WDW as it should have because... well, simply put... it was part of WDW. It put a sense of fun instead of a stuffy old classroom into the park psychologically and automatically made it feel different. Now perhaps they have to rely on Frozen in Norway to get that feel back. I'm just guessing here so lets not have a dagger throw over it.
Epcot is still good, but, not great like it once was. The Flower, Food and Booze took away it's sophistication and down classed it. But, it needed something because it wasn't drawing the crowds like it once did. As far as being too much of the same thing, those of us that were there when it opened or very shortly thereafter remember when Future World was also known as 'the land of the rubber stamped Omnimover'. The only thing different in the place was UoE with it's amazing ride vehicle, but, the show was a 45 minute commercial for Exxon. If you think that Ellen is a sleeper, it didn't hold a candle to the original show. Then there were the omni's SSE, Horizon, WoM, Imagination and a couple of years later the small but still omni Seas. Even the land had a floating omni ride. It would have been alright as far as I am concerned, but, you have seen the uproar that happens if Disney even thinks about using a previously used ride system. Somehow, people think that unless they reinvent the wheel every time, they have failed. In this case it is unrealistic expectations that are the failure.
