The first person to spoil it gets banned.

I'm on season 3, and totally agree about it being weak. When it's good, it's very good, but episodes like the one about the fly make me wonder why I ever bothered to watch it at all. Season 1 was amazing, though.
The Fly is a bottle episode apparently. A cheap episode meant to save money for other episodes... But yeah it was a bore. After ten minutes I started googling "worst episode of Breaking Bad" and Google autofinished it to "Worst episode of breaking bad the fly"...Even Google knew!!!!
But really, the episode made no sense. I know it's supposed to be symbolic and all that, but it didn't really seem like Walt's character at all. I've been up for 24 hours before and it didn't make me lose all common sense like he did. That wasn't him at all.
