Belgravia had lots of potential to be a cracking good tale, but it was so rushed, it felt like a wasted opportunity. The story introduced and wrapped up in 6 episodes. It would have been better if told over two or three seasons at least. There was no suspense because everything introduced in one scene was resolved in the next few. There was no time for any sort of character development so everyone was one dimensional; all good or all evil and greedy. It was almost an allegory. And it was so predictable that there really weren't any surprises. Nice for the costumes and some wry humor, but it could have been so much better.
