Dragonheart is missing! It featured the first full CGI main character along a real life actor in a real environment! Idiots...
Blade Runner being before 2001: A Space Odyssey. 2001 was a gigantic milestone in special effects, which may indeed having been a much bigger influence than Star Wars..
Metropolis was also a major breakthrough in special effects, and doesn't deserve a place behind films like Close Encounters of the Third Kind and Alien...
Forrest Gump also deserves a higher place, since it is the first movie which incorporated realistic CGI special effects to tell a story, which is very common nowadays.
I wouldn't rank the special effects of "The Terminator" influential at all. T2 however, was also a major breakthrough.
Their problem is, they don't seem to distinguish between most influential special effects and most influential movies. For example, I wouldn't consider Alien a classic because of its special effects, which were standard in 1979. Star Trek: TMP had much more sophisticated special effects. Blade Runner had great Special effects, but the movie was most influential because of its complex theme, cinematography, and atmosphere. 2001 however, is both known for its breakthrough special effects and its complex story.
There are other choices of films which I would consider for this list:
Flowers and Trees (1932) being the first released piece of cinema in full 3 strip Technicolor.
Willow (1987) had the first CGI morphs, which a lot of movies and TV series copied.
Howard the Duck (1986) had the first CGI wire removal (no joke!), which is basically a standard practice today in movies. It is not on the list because hardly anyone knows this fact, or the movie.
Battleship Potemkin (1925) for one of the first demonatrations of the power of cutting.
