Twists - BB16's haven't been unfair yet (expect for that awful quadruple eviction) and BB15 was too saturated with them

Theme - BB15 because Ashleigh became one of the greatest housemates be suss of it

Cast - BB16, BB15 had some gems but Winston, Hellen, Ash, Marlon, Steven, Kimberly severely damage it

Tasks - Both dire and awful. Channel 4 knew how to do interesting tasks.
