You do mention that you want to have a conversation about it, but It's going to be hard to connect with people who share your frustrations when you don't lay out a realistic view of things. I feel like you might get the conversation you want if you lose a lot of the hyperbole, otherwise this conversation will likely be around correcting the exaggeration. Condescension not intentional ;)
So yeah, I can't agree that things are getting longer and longer because it's just not the case. Things have been longer in the past. Also, I can watch almost every video they put out in well under 2 hours, because it's rare for something to be that long. I also can't agree that longer ='s worse, it's a case-by-case thing.
But is it time for shorter videos? Shorter QL's for sure, but that's been a kinda needed thing for a while (debatable). I think the new shows are the right length, they don't feel padded or over-stay their welcome to me in general (and still not 2+ hrs long :P).
