I certainly understand wishing that Europa had a more standout version of the product like Helix, but I feel Blue Fire served its purpose. It proved to the industry that Mack can make a 1) large, 2) launched), 3) looping coaster and it did it wonderfully. It did it so well that they've since sold 9 more variations of the ride along with several custom launched coasters. And it can be argued that the Blue Fire clones are the best coaster in almost every park they've been installed it.
I view them like I view Batman The Ride. Both have successors that are vastly superior (Helix, Montu, Nemesis, etc), but both are pretty good in the grand scheme of things.
