I've seen this several times, but The Husband had never seen it before. He objects to the violence. He also objects to considering it a Christmas movie because the season is incidental to the plot. Sensitivity to the violence is about the only thing I can think of that would interfere with enjoyment of the film, and I would argue that you'd have to be very sensitive. The Husband is quite sensitive to it, which is an endearing quality though I think it can be taken too far.
This is just great fun, and I never say "no" to another viewing.
Slant Magazine says,
while the film's showstoppers still dazzle, Die Hard isn't a great film simply because it delivers bang for your buck; it's great because its action is built atop a foundation of wit and emotion.Roger Ebert does not like it and concludes,
Without the deputy chief and all that he represents, "Die Hard" would have been a more than passable thriller. With him, it's a mess, and that's a shame, because the film does contain superior special effects, impressive stunt work and good performancesDVD Talk says it "set a new benchmark for action films when it exploded into theaters". It has a score of 94% at Rotten Tomatoes.
