I saw it too, and I think it's remarkably good!
There's a real lot of improvement from the earlier seasons: Better animation, better visuals, better musical score, and more importantly, it has some really good character development! They introduced some very interesting changes in some of them, and it's so exciting x3
I also enjoyed seeing all the callbacks from the original Lion King, TLK2, and several other TLG episodes (If you've seen all the episodes so far, you'll catch all the details)

.....OK, it does have a few cheesy moments that made me raise my eyebrow but it's still much better for TLG standards, so I'll forgive them. I take this over the new movie a zillion times more.

I've seen a couple of the new episodes now too, and I'm really enjoying this new arc. I can't wait either to see how this all ties in to SP
