This is a really awesome list - I'm proud to have seen all but two of them.

But I would also note that the 70s gave us both Star Wars ('77) and Alien ('79). Of the two of them I actually think Alien is the most significant because it was the turning point where we lost the rubber suits, army guys, professors making long winded explanations, and hormonal teenagers and started getting the darker and more serious sci-fi.

Disney's The Black Hole also came out in '79 and it is an enjoyable movie if you don't know anything about physics. It is a serious attempt at sci-fi and kept me on the edge of my seat when I first saw it.

Star Wars had a very specific kind of influence, in two main ways: 1) The lesser of the two is that it inspired a wave of imitators of its aesthetic, kit-bash FX, and space-opera elements throughout the 80s—pretty much all firmly in "B-movie" territory, at best; and 2) More importantly, it proved the box office viability and entertainment potential of the genre-pastiche/mashup film, paving the way for Tarantino and others.
