I stopped watching both Series 7 and 8 before the end - Series 7 due mainly to boredom and Series 8 due to exams. I caught up Series 8 on youtube though!

I enjoyed the first half of Series 6 but that series really did feel endless. We had a whole month of gender splits before the groups even merged!

7 was okay but could have done with a few more contenders- the fact Phil, Natalie and Ricky G made it so far tells you about the overall standard.

Of the ones I watched...

WORST
Series 7 (Awful lineup, awful winner, bad standard, too many pointless additions)
Series 11 (Full of gimmicks, and Natalie was always the best, but would never win (perhaps I'll eat my words tomorrow). Also Mark was shoehorned into being the comedy contestant which I greatly disliked )
Series 9 (Again, full of gimmicks, but a great final two)
Series 6 (Pretty good series, apart from Sergeant-gate and overmarking of Lisa - she was very good, but not worthy of 3 perfect scores, something unheard of in previous series)
Series 5 (Very competitive series, which I love, could have gone any way with the final 3. Also, the shock of Week 4 spiced it up a lot - we just don't get shock eliminations anymore. Also Alesha remains the best contestant we've ever had)
Series 10 (Absolutely loved it from the moment Isaw the lineup, to the spectacular final)
BEST
