I agree, it was a great film. I ended up seeing it I think three times, and enjoyed it all three There are a few moments of - wait, that doesn't make sense- but over all I loved it. I also thought the standard of acting was great. I hadn't really seen much of any of the lead actors in other things, but I was pleasantly surprised! Would anyone like to see a sequel, or prefer that it remains very stand-alone? Personally I liked it as a one-off, but can see another one being done well particularly as it's Mr. Nolan (who I do love).
