So the polycule IS canon actually

The one thing I will say to new Lost Boys fans who came into the fandom through the musical besides welcome is- please watch the movie! Do not dismiss it just because it was made in the 80s and seems corny (though it is, somewhat). The musical did a fantastic job expanding on things only brushed or referenced in the movie, but the movie is still incredible. There is a deep complexity to it. The original cast contains some of the most famous actors of the day, the bonds formed through that movie were iconic and well known, the soundtrack was revered, and the special effects and costuming were revolutionary for Hollywood. Pleade do not dismiss the movie! Watch it! It's incredible, it's wonderful, and it's addicting. DO NOT DISMISS STAR AND MICHAEL AS 2D!! The actors put so much work into representing them as complex and beautiful, and they really are. So love the musical- I know I adore it! But I deeply recomend watching the source material. After all, the actors from the musical didn't start from scratch.
