At least the layout is custom. That's nice to see sometimes. But yeah I've heard little good about this type of coaster, mainly the car being shaky and uncomfortable for the inversions they put it through.
I have no idea what the point of the MCBR is and the part after it, but everything before the MCBR looks cool.
Probably similar to the GateKeeper effect. The MCBR is less about separating meaningful sections of layout, and more about increasing train output by a small amount.
