I only watched Ashes to Ashes out of a sense of duty, really. It had some nice moments but came across as just too conveniently contrived: Gene moved to London, maybe, but Chris + Ray too? And, oh! Look! An 80s icon being unexpectedly encountered. Time after time.
But what an ending! Hilariously funny in places. A twist I really didn't see coming. And Gene, having been crucified by Lord Scarman, still manages to justify his entire existence with a snappy little sentence and the closing song* could not have been more appropriate as Alex realises she isn't just going to snap back to the future.
Still don't know if I'll watch the second series, though.
