Which one is the one you prefer

I love the Roller coaster, but those car crashes were horrible :s

Roller Coaster disarrangement

The Airplane explosion made me have a phobia of airplanes...

While the car pile up made me afraid to drive in a highway.

The Car Accident is the most belivable.. FD4's was such a big joke.

Car Accident followed by Bridge.

My favorite individual deaths are:
Tanning Bed Death (FD3)
Eye Lazer (FD5)
Elevator (FD2)

The cables on the wood slicing that guy in 5 parts

Let's just say I still refuse to drive near a log truck

How was the 3D in FD5 anyone? Were things coming at u?

The opening disaster in the second one is the closest that any of these films get to good filmmaking.

The car crash in the 2nd one was the most believable? HARDLY, none of it was believable (the logs bouncing, the cars exploding left right and center). The plane was obviously the most believable. I totally agree about FD4 though. Terrible. -.-'
Regardless, the 2nd movie's accident, despite being not at all possible, is my absolute favorite, followed by the bridge collapse.
