Y'know, with just some mist and blue lights would have been great. The last time I rode Nemesis Inferno the tunnel at the beginning was just a dark concrete tunnel. No red lights, no mist. But that was the first time I'd seen the effects off and realised that it was just a bog standard concrete tunnel, similar to Air's.
Now obviously, the tunnel is shorter and more natural light comes in from the end you come out of. However, if they did incorporate some of the fancy rock work, little bit of the same lighting they use when you "assume the position", little bit of mist, maybe a little music, I think everyone would be happy.
And while they're at it I think they should put some of the rock work around the under-the-bridge section. Theres another ugly bit of concrete with a nasty looking puddle to boot. Seriously, that puddle has been there since the day the ride opened! There was a some expectation during construction that there would be some sort of water element involved in the ride. That puddle was not what I was expecting.
In the coat you wore to Alton Towers is still the way I see you now...
