Halloween Ends (out Oct 13) is the thirteenth and final film in the franchise (if you believe the studio) and while the execution is iffy in places (stiff romantic dialogue, convenient timings, unexplained supernatural gimmicks), the four-person writing team have taken enough chances in terms of tone and plot to significantly differentiate it from others in the series.  The ending is a killer too (sorry for the lame joke)!  Grade: B+.
