For me, a SciFi movie must contain one of four basic plot elements:
- Time Shift
- Reality Shift
- Paradigm Shift
- Technology Shift
Three conceits I am willing to accept to suspend disbelief:
- Time Travel
- FTL (Faster Than Light) travel
- You can hear really cool explosions in space
I use five criteria when evaluating a SciFi movie:
- Enjoyability
- Originality
- Consistency of Internal Mythology
- Believability of Science and Technology
- Logic of Plot and Character Motives
