I was so excited after watching the pilot: it felt like the freshest thing I'd seen in years. A novel and stimulating subject (the relationship between an upper class gay guy and an asbo single mother). It had enough 'trashiness' to keep things interesting despite the underlying sentimentality. The script was tight and punchy, the acting was mostly good (though I must say Daisy Cooper already lacked range).
Ep. 2 was not as good but I still had hopes. By Ep. 3 it was quite clear the writers first came up with the characters, and that the story was an afterthought. I've just watched Ep. 4 and it's only getting worse: or rather, getting nowhere. Bogged down with unnecessary sidekicks, the main characters fail to acquire complexity and are merely pushed further and further in the direction established in the pilot. Their relation is also rather flat and dialogues lack finesse. It's all around disappointing.
The series was marketed as a 'punk-rock romance' and I think it's quite an apposite description. There are two 'punk rock' areas in London: Camden and Hoxton. The first is full of has been tourists and a few crusties, the second is full of bankers and art school hipsters. Rain Dogs is 'punk rock' the Hoxton way: it's filled with intriguing and colourful character, but ultimately it's all navel-gazing passing itself as rebellion.
