The thing that gets me about your list (this portion of it anyway) is that all of them seem to be easily updatable.
Obviously, Nemo is too new to be changed yet and Narnia probably will get SOME sort of update.
But Sounds Dangerous has been weak since it debuted, I figured back then it was a temporary place holder until they came up with a good replacement for Monster Sound Show. Now Sounds Dangerous has been there longer than MSS. I really liked MSS, SD not so much.
Backlot Tour is absolutely stale. Again, old props and sets seem like they would be easy to replace on a more frequent schedule. And, yeah, it's cool that Catastrophe Canyon can run and be reset quickly for the next tram. Until you realize that it's exactly the same thing every time. Now I only find it fun to do if I'm at WDW with people who have never done it.
I still like IJ in a way, mostly 'cause I like fire and explosions. That being said, I've wished for many years to have it updated to a different movie (please, not Kingdom of the Crystal Skull). You know it's getting old when you can pick out the "plant" as soon as they are called on and finish most of the jokes for them. Ditto to doing it with new people only.
