^Thirteen was over-hyped, however I still enjoyed it and would happily ride it again just for the fun of it.
Thirteen's impact on first time riders (who have no idea about the drop) is great, just listen to people's conversations as they leave the ride. I think "we've" had a distorted view on things by knowing what was going to happen beforehand.
Like I said above, I'd re-ride it happily, I thought it was fun and enjoyable. Sure, it's not the greatest ride, or the best family ride (and it certainly doesn't have the re-ride-ability that other rides have), but it's a fun little coaster. Yes, they over hyped it massively, and I do really dislike that, but I wouldn't say it was the biggest waste of time or space. That's just a bit dumb I think.
