As far as the Friday the 13th series goes, Part 1 is probably the weakest of the first 8 (after Part 8 the series just goes all to shit), but it's still an enjoyable film and interesting to see how the series evolved from a standard early slasher film to within a few years (Parts 3 & 4) being super awesome!
Somewhat dated, but still an enjoyable ride and a fun film to revisit.
