Lost Boys: The Thirst (2010)

The author of a series of teen vampire novels recruits retired vampire hunter Edgar Frog to help find her younger brother who disappeared at a rave.  She believes he was taken by vampires who plan to use him as a sacrifice at a huge underground rave about to take place nearby.

The new drug supplied at the raves is called Thirst.  Kids are given the drug which contains blood from the alpha vampire, thus ushering them into the league of the undead.

Along with Edgar, the novelist also hires a reality TV host who thinks this is like his show, a fake.  Edgar is not happy about this development, but decides to lead the mission as if he lets the obnoxious TV host go off on his own it will surely be a disaster.

Alan Frog, who was bitten by a vampire, contributes to the cause by making equipment that Edgar can use to kill the vampires.

While it can't complete with the original movie, it's still better than the sequel from a few years ago which featured random teens who come to stay in town and meet vampires.  The Frog Brothers are central to this movie, which makes it work.
