Before riding Maverick, I would have willingly argued with anyone that Millennium Force's layout was among the best in the roller coaster industry.
But after seeing the depth of variety found in Maverick's layout, I realized how much Millennium Force's layout lacked.
First, by my definition, your own personal experience of riding a roller coaster is a far separate thing from a roller coaster's layout. It is two ideas which often are blended together, in which a rider figures that a ride they enjoy automatically has a good layout.
I've come to find this is absolutely not the case, taking TTD for example. Amazing experience. Obviously not the most mind boggling layout of all time.
You see, to me a great layout is one which features variety, a constant flow of elements (preferably non repetitive)with a definite combination of twists and turns which fit together.
By this set of standards, MF's layout is alright, but is severely lacking in many areas.
In short, the entire layout is simply too drawn out. Though there is a flow, it always seems to be going more in slow motion as compared to other coasters; quick with their transitions and pace.
Luckily though, MF is great on creating a thrilling experience, so though the layout may be lacking, the experience you receive while riding helps fill in the cracks.
