In answer to the title, 16 is most commonly considered the worst but for me I'd lump in BB12 mainly because it mostly revolved around Aaron. And I hate Aaron. BB4 I haven't seen but it sounds pretty harmless, BB15 had some variety in its casting and if Helen hadn't won I doubt it'd even get much negative flack and while I still don't like BB16, it felt so alien to any other series of the show in its editing and twists that it roundabouts to being intriguing for me.
