Ahh as being a fan of the saw films I recommend that you see from saw 1 to 5 all becomes clearer. About the endings they all have bizzare endings if a better word could be used. Number 4 may confuse you a little as in it does and doesn't follow on from 3, but when you see it, you will see what I mean. And I do recommend Hitman, it's not bad I had some judgements before I saw it in the cinema, but I was impressed, so I bought the DVD. Tomorrow I am going to see saw 6
