I think it's been about a week since my last comment, so i'm updating.
Though last season was pretty awful with a 90% awful cast there was AT LEAST some interesting gameplay going on, and some characters which were extremely rootable. Candice figuring out the Moving Company and Nick's eviction, Aaryn winning HoH and the desperate power struggle in the house to save or evict Elissa/Nick, Helen's HoH and Jeremy's backdoor etc.
and the rootable characters of Candice, Helen, Elissa and Jessie...
This season, the gameplay is insanely dull. And it's because of CBS' idiocy. The producers are so dead set on "evicting floaters" (which is dumb to begin with. Dan, Danielle Reyes, Dr. Will and Neda's floater strategy is the most fun to watch anyway) that they made a twist which makes the HoH's cower in fear of ever making a play. For two weeks in a row four girls have been nominated - and Jocasta, Brittany, Victoria and Amber are all repeat victims because they're percieved as "weaker". Nothing is happening, and the weeks are routine.
Then the cast. They may be inoffensive, but they aren't even likeable. Donny, Amber, the now evicted Brittany, Zach at a stretch and Jocasta are really the only likeable characters. The others are all boring tryhards and they all just do what Frankie or Derrick want (even Amber is guilty of this).
In short, last season was bad but it was at least more interesting than this. Why? the 2 HoH's twist.
The 2 HoH's twist should've been that the two HoH's play in BoTB, and not the nominees. Still, though, they probably wouldn't try and make a move then.
Edit: I'm not saying last season was interesting. It really wasn't great. But at this point it was more interesting.
