This is by far the best film I have ever seen. I am astonished reading the reviews as this does not reflect how truly amazing and well made film that it is. It was so good that I forgot that I was watching a film at one point. I am also due to go on a cruise holiday next week and I honestly have anxiety about is as this film is so convincing.The actors are clearly highly skilled and deserve an oscar or a national history reward for best life documentary. From Megaladons to tsunamis it really couldnโt have been much more action packed.
