The protagonist is the most annoying character in each trilogy.
“Yippie!”
“But I was going into Tosche Station to pick up some power converters!”
I’ll leave it to someone who bothered to finish the ST to supply an appropriate Rey line.
“I bypassed the compressor!”
In all seriousness, these are my picks:
PT: Mace Windu (SLJ is a good actor, but he cannot pull off stoicism)
OT: The Ewoks (particularly Wickett)
ST: Poe Dameron (he should’ve died in TFA as planned)
