Stuntman/YMMV

Most Annoying Sound: Everything the director yells at you, but in particular for your failures.

Cut! That was too slow!
What have you done to the vehicle?

- Also the sound of microlites AND the constant buzzing of snowmobiles for reasons listed below on That One Level.

Tyrant Sabre: "That's.....a sound calculated to make you go insane."

Surprisingly Improved Sequel: Compared to the first game's horrendous paper physics, high difficulty aided by very strict limits, blocky graphics and incredibly annoying director, the sequel improves everything drastically so to lessen the frustration factor much more so.
That One Level: Hunted By Microlites from the first game. 80% of the people who played it usually give up around this point due to its absurd amount of demands. This Let's Play explains it in better detail.
- The final movie in the original game as well. It took the player of the LP linked above eight hours' worth of attempts to complete the second mission.
