I get the whole ride length, landscaping, interaction, spectacle thing with Colossus. I was walking around it earlier tonight thinking of it in comparison to the flat pieces of land Swarm and Saw are sat on.
I also have a soft spot for coasters (including The Smiler) that at least try to give you a decent amount of ride time. That's what annoys me so much about the Swarm, it's all well and good until it finishes quicker than a teenage boy with his best mates hot mum.
But let's face it, Colossus has always been far better to watch than to ride. It's a fantastic spectacle seeing it negotiate the cobra roll, twisting through those heartlines right next to you and thundering underneath as you look out of the shop window.
But the (cloned) layout is all show and no substance to ride. After a strong start with the first drop and loop it almost immediately let's itself down by rattling it's way over the most pointless camel back ever, which gives you about as much air time as gently driving over a speed hump. The Cobra is uncomfortable but bearable. Everything else is just pain and discomfort for the hell of it.
Also, no wonder the park ended up going with a Saw movie coaster. If jigsaw tried putting a Colossus restraint on a victim in one of the Saw movies, it would likely be banned by the BBFC for scenes depicting excessive human suffering. As for Saw the ride itself, at least it offers some sort of thrills whilst it's beating the hell out of you in true Gerstlaur style, Colossus on the other hand all pain and no gain to me.
