The early-mid 20s are generally considered the worst, yeah, but that doesn't mean none of them are worth watching (25 in particular is widely thought to be a return to form, and even the suckier seasons of Survivor are pretty good by reality TV standards)

There haven't been many returnees from Africa recently, but as a first-time viewer I'm sure it'll be fun to find out as you go so I'll try not to spoil too much in that respect!
