I remember I loved everything about it when I was a kid. I watched it all the time.
Last summer, Dave did a run of series 1 and 2, and I caught part of when they were running series 2, so I tracked down all my DVDs out of storage, and set about watching it again. Series 1 was better than I remembered, and I loved every nano-second of it. Series 2 was good. When I got to series 3, I gave up again because it felt like a totally different show. Series 7 was terrible, series 8 was a bit better, and I haven't dared go near Back To Earth.
If series 10 goes as promised and recaptures the magic of series 1, and it wasn't a 'Dave original', I'd trade my darts and pool cue (not really, but you get the point) to see it now. But it's a Dave original, there's been too much character degradation as well as story ass-fucking, so it'll be a massive disappointment. I'll give it a chance, but I'll probably resent it.
If you like the feel of the early series, I recommend the books. The last book was a bit of a let-down as it didn't seem to fit with the other 3, but I honestly think that the first 3 were fantastic, and if they'd kept with the level of them, they'd be my favourite series ever. Fuck it, even just cutting it on a hanging ending would have been good enough for that. Something half the standard of them would have made the series still amazing. The last book means that it was great. But the first 3 books: epic. The last one was too much like series 3 onwards where I felt it fell apart, the characters weren't who they were anymore.
Watch the series: Cat soon stops being a cat, to it's detriment.
