I watched The Blue Lagoon a while ago, and discovered during my thorough Googling on potential ending theories (did they die or didn't they?) that there was actually a sequel!

If you found the ambiguous ending in the Previous inspiring you'd better avoid this. If you liked the previous and don't want it to lose it's magic you'd better avoid this too. If you didn't like the previous you probably won't like this either, because it's pretty much the same thing, only now there's a mother with the kids instead of an old sea dog, and one of them just so happens to be a survivor from the prequel. You could say it's the Black Lagoon Legacy.

Compared to the previous this one isn't all as dark, and the sense of isolation feels further off as well. The characters (a boy and a girl, of course) grow similarly to the pair in the old movie, but they do their best to switch things up a bit. It's not bad, and the sceneries are as beautiful and exotic as they were before, but the mystery isn't there anymore, and the love feels a bit shallow... or forced. The mood's not the same. The magic's gone. It does have a more conclusive ending, a bout of action, and a few twists over the old as well as a message relevant to our our modern time... but it's not the same, and maybe it tries to cut off all lose ends too much, because when it's over there's really nothing left. The indigenous people. The bad guys. The good guys. Marriage. Death. Family. Everything's in black and white now, and mapped out so clearly there's nothing left to the imagination. No uncertain white blotches beyond our character territory.

It's like both sequel and remake in one, and if you've ever watched either one or the other you'll know neither sequels nor remakes tend to be better than the original. If you were content with that one, feel free to leave this one be. Apart from a young Milla Jovovich and Brian Krause you're not missing anything particular.
