Yes all of the missions followed the same structure:
Ride to mission point
Watch a cutscene
Watch Arthur get frustrated again
Ride to where the mission actually begins
Wait around for a few minutes
Oh no what? Something went wrong? No way!
Shoot your fellow Americans
Ride away
Listen to Arthur moan about Dutch and Micah
Mission Ends
I wish they would try a different approach, especially when they did such an incredible job with the open world.
