Lost Boys is an 80s film, cannot be remade.
Just like Back To The Future, Goonies, stand By Me, Mad Max 1/2 (even Terminator, (*early 90s is an exception and for good reason) similar. These 80's classic cannot be remade or have a sequel, no matter how good or bad. This was the era were the where a lot of the great aspects from the film came from the era, the cheesy clothing, lines, bad camera with no perfect lighting in every scene.
So for The Lost Boys this applies imo, the cheesy 80s style makes the film, just so happens to have a story/character behind it. You cannot replicate that.
The sequel captured nothing of the original, just like almost every other remake sequel.
*Early 90's still had that cheesy, bad camera style which i love.
