I've had the privilege of having traveled a lot and visited many great zoos throughout both the US and a few in Europe. None of them have offered anything close to comparable to the Safari at Animal Kingdom (and i have visited a few that did have smaller scale safari tour rides). You'd have to go on an actual safari somewhere in Africa (like Kenya) or Australia to get an equivalent or better experience.
Adding Indy to Dinosaur won't improve it, it will just make it quite nonsensical. Dinosaur already has a great base concept and a good start in terms of execution. The dialog could be polished without any issue, but i don't think it's a negative even as-is. They really just need to "finish" the ride as it was originally designed pre budget cuts. At least fill out the empty dark areas where they ran out of money. I don't want to get into an Indy vs Dinosaur flamewar about which ride is better, but Dino has its merits as well. Namely a handful of very impressive animatronics that (IMO) are mostly very effective at seeming real. I always enjoy riding it and think it's at least a very good ride, bordering on greatness and could easily be plussed to be truly great if they spent a bit of money on it (not adding Indy).
I've seen a couple of people claim DCA's Tower of Terror was better. I just don't get any of the arguments at all. It really just seems like the same experience with less overall ride, scenery, surprise and overall impact as WDW's. The 13th floor where the elevator leaves the shaft was a unique surprise that left a big impact on me when I first rode it, setting it even further apart from normal drop rides and enhancing the atmosphere tremendously. It's similar to the arguments from people saying WDW's Pirates is better than Disneyland's. I've seen a few people claim that, but i'm just not able to fathom why. WDW just feels like largely the same experience in a very cut down form.
I don't like Kali due to the shortness and an inherent dislike for that type of ride system. But it IS one of the better of its kind i've seen due to the scenery. Still I wouldn't miss it.
I DO really like Navi River a lot. I realize i'm sort of in the minority on that one (and it IS too short), at least in terms of how much I like it. I'm pretty meh on simulators, and Flight of Passage didn't win me over there (it's a decent and enjoyable ride, but not a priority for me at the park). Navi River I found lovely, charming and peaceful. But again, weird minority opinion from me.
