Utopia was pretty cool, quite weird, and has a pretty high body count for a British series
Utopia was great fun – really liked the lengthy episodes, pretty much all feature film length but didn’t feel that long at all
Luther was great but I thought the first series was much stronger than the second.
One thing thats frustrating about british stuff is the series are so short compared to US stuff. 6 episodes a season, maybe 3 seasons if you’re lucky.
One exception is Ideal, quietly that grew into a massive series – just shy of 60 episodes, 100 characters. Although its not really in the same flavour as much of the above if you like it then theres lots of it to like.
