Star Wars

The standard for sci-fi before Star Wars was Star Trek, but typical sci fi movies had terrible plot, reality, story line, -all hanging on a great idea.-for example:
an astronaut, wearing a effing FACE SHIELD, talking to a killer blob, on Mars, in English negotiating a philosophical peace.
Lame,lazy fiction, especially after Jules Vern, and countless others.
Even "screamers" (no it's not a **** movie) ?
I actually like that movie, but the whole "smoking to counteract radation" was a bit thin
