Here's my thoughts after riding it today. So if you don't want spoilers, unplug the internet.
The theming is really good. The back story isn't overly complicated, the centrepiece of the ride looks great and the pre-show is short, sweet and goes straight to the point. The station also looks great inside, and the soundtrack is superb (wouldn't expect anything less from IMAScore!). The staff were still getting to grips with the pre-show sequence, but once they nail the operations down, it should get through a good amount of people. Especially as the trains are sans seatbelts, like Wodan at Europa-Park.
The ride goes better than those first awful test videos suggested, and the swooping downward s-turn is good fun, but it certainly doesn't fly around all the bends like it's bigger GCI cousins. That's not to say it's bad. It isn't. It's got the usual little pops of GCI airtime, but it rides pretty much how you'd expect if you've done your fair share of GCIs. I'll be interested to see how people who've been on Heidi/White Lightning and Invadr rate it. The closest I've done is El Toro at Plohn, and that was a much better coaster.
For the first time, it is worth the wait. The way the whole package comes together ****s all over Thirteen, and families will love it as a step up from the mine train next door. It is quite short, and yes that boring corner is boring. But for what it's worth, it's a fun experience that will make you want to buy some of the fab merch on sale once you get off.
It will of course be obscenely busy this year, and rightly so with all the hype, and I couldn't see myself waiting for it in a massive queue at the height of summer. I would be willing to wait a while for a night ride during Scarefest (I'll see about Fireworks weekend. As Wicker Man is next to the lawn, you'd have to be tactical where you stand because that will be a disgusting queue once the firework show ends).
