Paradise - the search of it. Where are we at home? Could we live anywhere? Could we do without all the technical gadgets? I'm not saying living alone (though for some that may be the way to do and live it), but living without certain things that make life "easier" ... or at least that is how we perceive it.
Nature can be quite the enticing thing. And it is in this movie too. The Beach that lends the movie the title is quite the sight. And for a vacation spot ... I mean you could do far worse. Now there had been rumors that the filming was done on a beach or in a place that was supposed to not be touched by western civilization ... I remember Leonardo DiCaprio getting quite a lot of heat because some activists were not happy with him.
I can't confirm if they actually loitered or ruined nature in one way or another. If that really interests you, you surely will know a way to find out. I just thought I give an insentive to those who are interested in behind the scenes thing - real or not. Then there is also those who may take offense in the portrayal of certain animals (feeding into our fears and portraying them way more evil than they actually are - talking sharks here).
The movie itself is quite the decent thriller. Because the Paradise is not all fun and games. It is also filled with cliches and quite the predictable plot. Still the movie knows to hold up its tension and has quite a few gruesome moments too (graphic violence that is). Not a bad movie then, but not a masterpiece either in my book (while I came to finally admire Leo, his character here is not as relatable - choices and such. There's a general detachment from it all)
