Raptor is quite simply the worst B&M Invert I've ridden (yep, worse than Silver Bullet, which I find under-rated)... And the less said about Mantis (and for that matter, Mean Streak) the better...
Millenium Force(less) is outstandingly over-rated as well... I just didn't get what it was doing, and it has more long pointless straights than Shockwave at Drayton Manor...
Magnum is alright, but on the same trip I had done Phantom's Revenge shortly beforehand, which is tons better...
the family coasters are also pretty poor, with only Blue Streak being better than decent... Disaster Transport was also a good ride actually, but since it's gone now it doesn't matter... Iron Dragon, Gemini and Cedar Creek are all pretty poor coasters too...
TTD, Maverick and Wicked Twister are the 3 best coasters there... That's my view on the park, which is exceptionally overrated...
Magic Mountain is a similar situation, though I haven't been since they've changed X, added a new wooden coaster and removed a few others... Very over-rated rides, quantity does not equate to quality...
It shares a LOT of similarities with Thorpe does Cedar Point, but 3 quality rides out of 15 (discount Gatekeeper, although it will probably be very good) is a poor ratio for any park... It's a thing you see in a lot of American parks where there's very little quality outside of the major rides... Especially when you look at the European parks and see a complete difference in style and effort...
