Peter Pan and space mountain. Peter Pan looks like a carnival ride through and through. From the AAs to the ridiculously awful audio (captain hooks voice lol) it's just bad. It doesn't help that it's wait times are one step above hell either, it's a childhood classic but it hasn't aged whatsoever.
As for space mountain good lord, I really want to love this ride so much but I can't. Insanely jerky, barely any scenery (besides cool queue minus games) and it's overall just a bleh experience. Go on the DL version to see the true SM experience. Honorable mention rockin roller coaster
