How does everyone think this year's BB has compared to the previous two? I think it's been pretty dull really. no main personalities have emerged and overall its been generally boring

U R right. The divide was a big mistake. It made tension and conflict the central themes. In previous years there was a lot more incentive for HMs to work together. Of course they got hacked off with each other sometimes - but conflict was really only the subtheme.

Also no den this time, not much by way of entertainment provided - so of course they were going to get on each others' nerves.
