I think I watched it even quicker than you did, except for the last half of season 5 which I watched as they premiered. I was recovering from foot surgery and tore through it on Netflix in about a week. Hell of a ride
To answer your questions, Gus was probably gay but I don't think Beneke came along until after Walt Jr. was born.
'm surprised by how many people were actually pulling for Walt and hated Jesse. I spent all of season 5a and 5b loathing Walt and wishing he would die a horrible death. I wonder if I have a different view of it because I was able to jump from episode to episode immediately without having to wait.
I found myself pulling for Walt to suffer for what he had done(to a large extent he already had by the finale anyway), but on his own terms. I certainly didn't want him done in by the Nazis and Todd. Once Hank died it wouldn't make sense for the cops to get him. If Walt was gonna be arrested then it would have to have been by Hank. Also didn't hate Jesse except for when he teamed up with Hank.
