It still wasn't a great ride, but it had a clear theme with more effects. It's been diminished over the years, which is especially bad for a ride that wasn't special to begin with.
Grizzly is definitely longer, and has more drops. So it at least has something over the ride experience of Kali. I also only waited 10 minutes for Grizzly, as opposed to the 50-60 I waited for Kali. Never again.
Both should be replaced or altered to have more interesting scenery.
