I bought the 'book' box set which covers the series up to 'Jason Takes Manhattan'.  It's an economical was to pick up 8 'classic' slashers. Part III is presented in startling 3D. The last 15 minutes or so of Part VII are surprisingly good. The commentary for Part VI is worth a listen as is the track for the original Friday the 13th. The movies are what they are…bad slasher pics. If your tolerence for slashers is high this box set is definately worth owning but if you thought they were crap 25 years ago they've not improved with age. Much of the bonus material seems fan produced & is rather repetative & tiresome, especially the faux 'Friday the 13th'esque extra murders. A few discs contain raw footage of fx ultimately trimmed by censors. It's been a number of years since I watched the series & was surprised at how much I enjoyed seeing Part 1, 3 & 6 again.  In recent years "freddy Vs. Jason' & the effective 'friday the 13th' reboot have been a breath of fresh air for this tired old series.
