If the thread is expanded to worst professionally prepared films then you must watch, Rescue 90 - J+++s acting - epic!
Also the disorientation film shown to us at Linton, late 60s, with the classic and memorable phrase from a F100 driver, "Git on the gages Frank!" - followed by CRUNCH/Splat.
12 O'Clock high. We were forced to watch it at OCTU but only in two to three minute scenes.
Airwolf -AAARGH.
But the flying scenes in B o B and Apocalypse Now - muy bueno!
