Its awful. Absolutely terrible.
Went there on me birfdee (Mrs trying to reclaim my youth) a few weeks back.
Queue up for 40minutes...go into a lift with flashing lights. Walk into a "science lab" with an egg in the middle, sit around the table. Flashing lights, loud noises, goes dark...you drop 3 feet. More flashing lights, bit of water spray, get poked in the back, get your feet "mopped". Go back up the 3ft, light come back on, walk out. All done in less that 5 minutes.
No joke. Its shocking and not even a "ride". Its basically someone turning the lights out and going "boo"
