No, it's actually a bad ride. In every way a ride can be a bad ride, MDMC is. There are 2 things going for it, they are
1. The side cars.
2. The way loose articles are accommodated on a ride with seperate load and unload stations.
That's the plus side, on the downside you have a slow moving queue, partly brought about by poor station design and partly by awful restraints, managing somehow to be unintuitive, uncomfortable, overly restrictive, unaccomodating, and a manual handling hazard for staff.
The layout of the ride is poor. A lot of rides try to increase the sensation of speed by getting lower to the ground and having more intricate manoeuvres as the ride goes on. MDMC seems to get higher off the ground, so even with tighter turns it just has no speed to thrill you with in it's latter stages. What is its target market? Thrill seekers? Dreamworld say so, but launch and first turn aside, it just isn't thrilling. A family coaster? The height requirement is 130cm, one of the tallest in the park, which stops a lot of small kids from riding. It's clearly meant to be a thrill ride, it just didn't work out. The side cars somewhat negate this, but they aren't what the meat of the ride is supposed to be.
Maybe it just fits into its surrounds so much that it adds to the ambience of the park? Not even. The coaster itself is largely hidden from view so it adds little Kinetic energy to the park, the themeing is at odds with the area it's in, and it takes up a massive amount of prime real estate with its spread out layout.
Seriously, in every way that a ride can be a failure, MDMC manages to do it. That's why it's listed as people's least favourite.
