Series 1: 9.7/10:The best series, with the most funny and hearty moments. Also the best 'gang'.
Series 2: 7.2/10: A massive decline from Series One, as they chose to bring back Ben, and introduce dreadful characters like 'Amber', and getting rid of 'Louise'. And a lot of characters didn't return.
Series 3: 7.0/10: An ok series, again a decline from Series 1 and 2. Too many new characters, with Shelly, Layla, Hayley, Michael, Crash, and Jackie coming in this new series. Adele and Ben are nowhere to be seen, Ben is mentioned in episode 1 as going off to boarding school, then is seen in a photo in episode 10, and isn't mentioned again. Adele is not mentioned at all. Luckily, Louise stays on as a reccuring character for the series, but, along with Nathan, Shelly, Michael, and Justine departs at the end of the series. Tracy and Duke and Cam are the only character to have stayed from the first series.
Series 4: 6.8/10: A not very good series, mainly because of the Wellards, the new house, and Tracy and Cam beginning to be absent in most episodes. There are some hearty moments, like Layla and Hayley's goodbye.
Series 5: 6.2/10: The worst series, mainly because of the absense of Tracy. Good ending, though.
