I forget about Toy Story Mania because I think it's absolutely terrible and should be demolished. It was fine when it first opened (even then it was just mediocre, but fine), but now it's basically playing a 15-20 year old video game. You could play a more advanced/fun version at home on your couch. I realize I'm in the minority there, though, and plenty of people seem to love it.
I don't think Smuggler's Run is very good either. Being in the Millenium Falcon cockpit is great, but the ride itself is, again, a mediocre video game. It just does nothing for me. Slinky Dog Dash is fine, but it's essentially just a standard family coaster you could ride at any number of amusement parks around the country. It's not worth the wait times.
Tower of Terror is phenomenal, no argument there.
