It shouldn't be 68 vs. 90
Even though Night 90 is a remake of Night 68, I think it is best viewed as a stand alone piece. To refer back to the title of this reply, I don't think it is wise to compare the two, nor do I think it is fair.
I enjoyed Night 90 very much. I think it has many admirable qualities, both for technical and entertainment value. On the technical side, I liked the cinematography, particularly the compositions of shots that took place outside the house. I also like the lighting. It conveys a very dull feeling for the farm, which I think actually helps the mood of the movie overall. The make-up was great; I think Savini's vision for how the zombies should look was bold and daring. The fact that he didn't "overdo it" with the gore was a good choice, in my opinion. The glazed dead eyes of the zombies were a plus as well.
The acting was fine - not great, not inferior. For the script and the scenario, I think the cast did a fine and believable job. Kudos to Patricia and Tony in the lead parts, but I also think the supporting cast (especially the actor who played Mr. Cooper) were true to the spirit of the script and story.
P.S. - I like the fact that Barbara ends up shooting Cooper in the end. Just desserts, if you will allow me to use the phrase.
My 2 cents,
M.C.
