I don't think saying "just don't subscribe" as a way to wave off criticism is very good. The guys would certainly not want people to just stop subscribing.
It does feel very different to when the site first started. You can tell when they're actually enjoying a game and when everyone is just bored, trudging through a game to eat up time. It's a bit weird too because Unprofessional Fridays is a show where they can bring literally anything they want but somehow half of the show doesn't seem very enjoyable for most of them.
As much as they like to scoff at the idea of doing another Endurance Run, I really do think the site could benefit from having at least one long playthrough of a game happening at anytime. Even something like Vinnyvania was super enjoyable even though he only played that a couple of times. It's because the audience could feel Vinny was invested in the game, he actually wanted to beat it. I'd much rather watch them do whole playthroughs of games they actually enjoy, than them just randomly bringing in something to Unprofessional Fridays that they have no idea about and end up yawning at.
Not that I mind seeing that it gives us gems like gangbeast.
