You are saying about B&M and Intamin, and comparing them to being boring or not.
Well for me, B&M boring rides are I've been on are:
Sheikra
Raging Bull
Talon
Not Boring to me are
Superman Ultimate Flight
Iron Wolf
Chang
Montu
Hydra
Riddler's Revenge
Batman the Ride
Goliath at SFOG
Diamondback at Kings Island
Raptor
Kumba
Scream!
Intamin Boring Rides are
Millenium Forceless
Superman the Escape (Magic Mountain)
Not Boring Rides are:
La Vibora / Rolling Thunder
Top Thrill Dragster
Superman: Ride of Steel (SFA)
V2 / Steel Venom / Wicked Twister
Disaster Transport (though not a great ride like La Vibora or Rolling Thunder in my opinion)
Maverick (barely a good ride because of "Mr. Freeze" part, but I will have to ride it again.)
For me, there are a lot more B&M rides I've been on than Intamin, so naturally B&M would have more boring rides because they make more I've been on.
