I don't think I'd be as interested in the show if it wasn't for the feeds. They add a strong sense of realism for me, and be able to see everything that goes on really enchances the experience. It's not just about the fights and parties, although that alone is a good reason to watch, but the also the ability to "play along" and follow every move as it takes place. I don't know - it's definitely something I NEED, though.
Plus, it's a good excuse to stare at shirtless guys all day.
Last year would have been more fun if Frankie didn't ruin booze deliveries and feed polls, and if Derrick didn't constantly suck the life out of every event and possible game move.
BB15 feeds were kinda golden, though.
