I absolutely loved it, to my suprise! I heard such bad things about it and expected it to suck but decided to watch anyway just for Charley, but to my suprise it was actually very enjoyable and totally underrated. No way is it '****' by any means.
Yes it had its dull moments near the end, but as a whole it was a great series with many great housemates. Everybody was quite memorable and it was a generally a very fun series with great memories. I don't understand all the hate for it at all, but I guess it's the fact that it came after BB5, BB6, and BB7 (3 OMGAMAZING seires) so it didn't look as good in comparison. But it was definitely better than BB11 and I know people disagree with me but I may have slightly enjoyed it more than BB9 even.
If I were you, and you haven't seen BB8 since it first aired, I would give it a rewatch. At least up until Charley and Chanelle leaves. It will be worth it, it's HIGHLY entertaining.
