“Friday The 13th Vengeance 2: Bloodlines” (**1/2 out of four) was an overall proficient spin-off of the classic horror series which is a direct sequel to “Friday The 13th VI: Jason Lives” about Jason Voorhees’ father (C.J. Graham) who resurrects his son (Jason Brooks who also directed) to finish off the Jarvis family once and for all and slaughter lots more teens but things get awry when Tommy Jarvis (Thom Matthews) shows back up leading to a final showdown to the death. Crudely done from the outset with some mangy opening scenes but once it gets going- it does deliver more than its quota of gore and creative kills for series fans. Many kudos also for hardcore “Friday” followers, such as the return of Matthews and Graham (who played Jason in “Jason Lives”), the return of Darcy Demoss also from part VI, and the return of Harry Manfredini’s now-classic score!
