Let me try and explain. If I watch lord of the rings, or game of thrones etc. I suspend my believe in certain things and use my imagination to immerse myself in the world. If Someone suddenly appears with a machine gun in this world, it would completely break the immersion for me and the show would become unwatchable.
I can overlook certain plot holes, or subtle inconsistencies, but there is a line where if it becomes too much, I can not immerse myself anymore.
An example for myself would be the Movie "Independence day". The first part of the movie was so riveting, but then someone could suddenly device a virus to infect the alien's tech, as well as all nations being able to shoot down the Motherships like the US's remaining airforce (The best in the world barely being able to do it). So this was just about the line in the movie for me. So I could still watch it, but it was starting to break the imersion for me.
So you see it's all relative. With or without the patch Summertime's saga imersion in this one arc is becomming tough to overcome for me.
