all-stars is horrendous, from what i've heard
but world's apart wasn't bad at all. the episodes were interesting and it was a good cast of characters, just all the good people went home (i literally liked/was neutral about everyone that went home before tyler)
Okay well my bottom 5 are
Redemption island
South Pacific
Thailand
Caramoan
Idek...
Maybe one world but I liked how the females crushed it well mostly kim
