Naw, the absolute worse are dream sequences and flashbacks that make you move at a reduced speed. shyts are boring and always too long.
im shocked it even took this long to mention shytty ass dream or fantasy levels
play a whole game as one thing... then here comes the trippy music, someone calling your name, foggy weather, wavy looking graphics, disappear into smoke enemies, endless "fake you out" ways to turn/jump/die, all for you to wake up and keep playing the game exactly the same... usually with zero point to the story
