I thought there was plenty of extreme rides, I especially loved nemesis inferno, stealth and the saw maze. You gotta see the saw maze absolutely fantastic haha. Although one big thumbs down goes for their mile long queues. I queued for 2 hours just to get into nemesis inferno. I queued for 40 minutes just to get into the ride called 'the fish. I queued 1 hour 45 minutes just to get into stealth and finally I queued 1 hour 55 minutes to get into saw maze. All in all I managed to go onto 4 rides within a 6 hour period. Remaining minutes I looked around for rides with decent waiting times, obviously I was asking too much.
Verdict: Will be going again, when school holidays are off.
