I still like the Swarm, but can easily say there are coasters with better theming and/or layouts.
For example Fenix at Toverland. It isn’t the biggest or longest wing rider out there, but what it achieves in it’s duration is simply great, as it elegantly yet forcefully flies around it’s surroundings.
The queue, theming are surroundings are simply magical with it’s charming, mysterious and whimsical details that are accompanied by an arguably lovely soundtrack (I know some of you will disagree).
I won’t deny that I still like the Swarm, but it is comparatively lower on my favourite list. About 3/4 years ago it was still in my top 10 coasters, whereas now it is only in my top 30 at best. I really don’t think the appealing state of the remover theming in the station has helped as it is now a right mess.
As for ‘’elaborate/impressive’’ themed rides in Europe, I’ll drop a few examples even if they’ve already been covered.
N.B excludes Disney.
