Jeez guys, this is one echo chamber full of negativity - talk about "love us, hate Merlin" sometimes.
So, no. Bouncezilla isn't a multi-million pound rollercoaster or flat ride. No it isn't an immersive dark ride. No it isn't long term. It is as every bit garish, loud and obnoxious as it suggests. It actually does what it does well and although the location isn't perfect, it's something different to do in the park (along with GameFX and the Lunar cinema too). At the moment, there are lots of rides and games stalls, but very few attractions or experiences. So, it's nice that Thorpe are exploring the possibility of things outside of rides. It's just a shame that some people interpret this as cheap, low effort and poorly thought out. Ultimately, this seems to be popular with the public and I guess that matters more to Thorpe than some die-hard forum keyboard warriors out to criticise every aspect of the park and Merlin. People seem too willing to pick them apart for every tiny detail not to their taste, but seem to be unwilling to recognise when they do well or congratulate them for at least trying something new.
Given that DBGT and The Swarm didn't generate the ROI they had hoped for, allowing Thorpe to explore other aspects of their park and guest profile is actually wise. But of course, Thorpe could build an RMC to rival Steel Vengeance or a Hyper that would challenge Hyperion and they would still rubbish it "because it is Thorpe".
