All along I have been thinking Holly Aird was too big an actress just to be sat there (there are a lot of familiar regularly second and third string British actors seen here but I thought she deserved a bigger role) but the closing scene was still a bit of a surprise.
The changing of the scenery depicting various seasons seems strange considering only an 8 hour flight from Dubai to London.
So the two guys that were tied up before Sam were gagged but, strangely, big mouth Sam wasn't.
The two guys have now had their gags removed unless, that too, is a continuity error.
The quality cast sees through the poor writing.
