I really don't see why its being judged so much before its even near opening.
Merlin get an awful lot of stick on here and I'm not too sure why, compare pre Merlin rides such Stealth and Rita to say The Swarm, Smiler and even Saw, there are massive improvements in terms of quality and effort. I see no reason at all why this area won't look good when it opens to the public which is what still over a month away?
