As a 28 year old who has been going to SDC since I was born, I like the changes. Now with that, I have many fond memories of the "old SDC" with LR, FITH and FM. I remember being terrified of LR and FM because the queue lines were super dark and enclosed, but in my opinion, every change that has been made has been for the better. I was mortified when Buzz Saw Falls was removed, but it made room for my favorite ride on park. Now, I understand it was removed for reasons not related to age and being "old". Or when the park got rid of the old green trams and trolleys, heartbreaking.
I think MRF is way better than LR, even though I miss the classic LR, especially the cave. If SDC continues this, and I think it will, the new FITH will be just as good or even better than the old FITH.
I love the idea of a newer, larger train station. Even though I have many memories of the old one, it has run its course. IMO. Having to wait sometimes all the way to corkscrew pass is crazy and if you're just walking through the area, it can be extremely congested.
I personally think an area that needs an overhaul is the entrance. When it's a busy day, the ticket booth line is insane and just trying to get in through security and turnstiles can be tight.
One thing to keep in mind is if the turnstiles don't move, there is no SDC. We all know that. With costs going up it creates the need for them to turn even more. If this is a way to do that and get a nod to the old SDC, then it's what the park has to do. You have to adapt and create new things or you become old, stagnant and the same ol' SDC. Regardless of how much we all love the old SDC, the newer generation, might now and that's the future.
