BB8 has gotten a lot of critism, and the ratings have been... how do I put this.... cr*p. But personally Ive really enjoyed BB8 and heres why:
Its been a normal series. Theres been a few [pointless] twists, but they have been short, and mostly been mixed in with tasks.
The HWH was a disaster but every series has its mistakes.
Its been original. Theres been so secret house evictions. No secret house focusing on one person (Makosi/Ash)
Its been unpredictable. No-one predicted fake week, until recently theres been No favourite.
And it looks as if the winner is gonna be a 'first'
Its either gonna be the first ever twins to win, or the first ever newcomer to win.
Its had its downfalls (fixing it for Charley much?) but, overall its been a good series imo, and theres still a couple of weeks left.
(sorry for the essay
