I've always loved Universal California and always felt the balance was perfect there. Such balance in the offerings. Backdraft is awesome, a great short presentation in movie making that DS lacks. A fantastic backlot tour with "extras" like Jaws, Kong, Collapsing bridge which Disney needs to challenge. Finally a fun "kids" type ride, ET, is US equivalent, if it hasn't closed down, although a Muppet ride might be the like attraction here or how about a Monsters, Inc. "door" ride and place it in the Playhouse Disney area if room to do so.
I LOVE Indiana Jones, but the stunt show was only so/so for me. Bring on the Indy Ride, which at DL is my favorite. Change the story line a bit but what a great attraction for a part of the park not in the ToT, RnRC area. Add another stunt show/live performance show in another part of the park to eat up crowd.
So many possibilies, but improvements are needed for the whole family experince. We spent the least amount of time in our last trip to DS, because there weren't what we felt were alot of must do agains with a 5 year old. This year she'll be 6, but still don't see alot of time spent at DS as opposed to the 3 other parks.
