Sorry Liam, I don't agree. Merlin in general, have been pretty spot on with their rollercoasters. Each one may have flaws, but on the whole they are good attractions, I love Raptor, The Swarm, Thirteen and The Smiler. I don't think Oblivion is a hint at what the parks may come up with in the future, Raptor is leagues ahead of The Swarm and Daemon in terms of theme, layout, interactiveness and enjoyment for example.
When it comes to their rollercoasters, I like them. it's all the other rubbish like I'm a Celeb or Angry Birds Land that I don't need to give the time of day.
