I just watched the longer video with the children. My gosh, they said DLP looked better back then (they are 5 and 7 and had no prompting). They were particularly taken with the Dapper Dans (just like in America, my son said). And they loved the storybook show (they asked why they didn't do it now - I replied that is where you can now meet the princesses, my daughter, aged 5 and who likes princesses, said "awwwwweee I want the storybook show".). And my son was intrigued with the space lunar module at the enterance of Discoveryland. They both were blown away with MSEP (which had more performers here than in the final years) and real fireworks (not the small junk in the Enchanted show).
Then I was taken by the lighting on Space Mountain, the cleanliness of the Hyperion airship, and all the amazing lights on Main Street moving around.
This is the DLP I fell in love with in April of 1992 and felt was getting better and better until just after Space Mountain opened. Fromm 2000 on, I agree it started going down hill in a big way. The 15th restored some of the quality, but not quite. And now I am resolved to the fact that a generation has been brainwashed to think Disney parks = toons. This has only really been the case for the last 10 years or so, the 40 years prior to that Disney used to be about blow them away themed experiences. This is why I get angry at some of the fan community, because I feel they are a big part of ruining the place.
Getting excited about meet and greets may be fine for you, but that is all disney are now focusing their attentions on. And that ruins it for those of us who like the traditional Disney park experience. I don't think they should get rid of all the characters, as I recognise that is highlight for many, but I would like some balance please.
