I put my hands up and say "Yes, I did say it was crap" on the first go, this is probably down to the god-awful marketing of this ride from the outset.
It has been over-hyped to the extreme, and in a nutshell its a bland coaster with a semi-ok dark section.
The theming around the queue line is pretty good actually, with nice little touches here and there with the old alton towers van being used in one part. The Station building is very nice, cant fault it really although, its not very well lit in places, and you struggle to make out whats actually in there i.e. The compressor in the corner. (The badly lit problem also goes for the part just on the right as you come back into the station.. What is that stuff you cant see?)
It will be great to see the tesla-coil working in there, when its ready, from what I can make out its surrounded by a metal cage so the coil will arc out to the metal making a great centre piece of the queue line. One thing to note also the station interior has a hint of SAW: The ride.
Now onto the coaster, well... its nothing special lets put it that way. Think a smoother RMT and your about there, the first drop doesn't work as it has a trim break half way down, the airtime hill is nice and works very well, but you are actually coming into the "station" after the top of the lifthill in approx 20 seconds, its just TOO short.
Dark Section: Now, this is "ok" some nice theming inside, but does need animatronics in place and the audio needs to be louder also. The effect works, and works well, very well infact. So thats its saving grace.
The underground tunnel: This is my favourite part of the ride, but it needs something in it, maybe ice-mist (like in Valhalla) or curtain flames across the ceiling, but a dark tunnel is just boring.
On the whole, its good. Its NOT A secret weapon, AT ALL, but a good Family coaster, with a good dark section. I ended up riding it 4 additional times after my first go today. And it kinda grew on me, but like I said, the over-hype ruined it for me.
