Dreamz and Rocky (along with Lisi) were both pretty darn hard to watch and stand. Especially since Dreamz actually took himself seriously.
Sure Tocantins brought us Coach, JT, Stephen, and the good Tyson, but Taj is meh, and we got annoying people like Erinn, Debbie, Sierra, and others.
As for Samoa, aside from what I touched on, the Foa 4 were totally meh and not really that likable except for Natalie. I mean, Russhole is by all accounts the most repetitive and one dimensional character I've ever seen. I mean, even Osten from Pearl Islands, who's whole stoyline was him whining about wanting to quit had more dimensions and more than 2 different confessionals. All of my favourites were either on Galu or Betsy anyway, lol.
I find a lot of the strategy to be good, there are a lot of good characters to suit just about anybody's taste, and the editing is a LOT more fair and equal than any of the Russell seasons editing was, which is such a fresh change.
Of course, some of my favourite seasons are Borneo, Pearl Islands, Vanuatu, Guatemala, China, and pre-Final 6 Gabon, so...
