I'll put them in order methinks:
1 - Federico (BB4) - He was quite funny, and one of the more interesting HMs of an otherwise very dull series.
2 - Roberto (BB6) - Had nothing against him. He was ok. I remember being slightly shocked when he was evicted over Derek I think it was.
3 - Sezer (BB7) - A HM that I loved to hate!
4 - Cairon (BB10) - Didn't really care for him, but he was entertaining to an extent, and had his moments.
5 - Andrew (BB1) - Him and Sada were the only HMs I never got to see (only started watching BB1 after the first 2 evictions). However, everyone ranked lower on this list I dislike. So Andy automatically ranks here. Plus, from seeing clips of him, he seemed kinda genuine really.
6 - Stuart (BB2) - He wasn't that bad really, but he did act out of order with arguments, thinking he was superior etc. Overall, disliked him, but nothing major.
7 - Lee (BB3) - Again, disliked him but nothing major. His VT was disgraceful though.
8 - Seany (BB8) - This man royally failed. He thought he'd last long, but he was out first opportunity after he entered lol. I didn't like him for some reason, but again, nothing major.
9 - Mario (BB9) - Couldn't stand him. He was absolutely boring. I wanted him to be the first ever male 1st evictee dammit.
10 - Govan (BB11) - A terrible HM. Was ruining my viewing of this series with his pointless bitching, and I'm so glad he's gone.
11 - Marco (BB5) - Do I even have to give a reason?
