I grew up never seeing The Blue lagoon until recently, actually its a pretty darn good film, but the sequel sucked from the very first image of different boats and of course the two kids(parents) DEAD.
Worst sequel I have ever seen, Return to Blue lagoon, what were they thinking?
And any films out of the former Soviet union are all crap, like Ghost Rider II.
I don’t suspect you watched the Blue Lagoon version made on Life Time, like most of their movies, it is comically bad.
