THE LIST OF SCIFI MOVIES.

List of Good SciFi movies

• X-Men - it's highly possible to happen because they possess special powers due to their possession of the "X-Gene," a gene which normal humans lack and which gives Mutants their abilities. Early on, however, the "X" in X-Men stood for "extra" power which normal humans lacked. It was also alluded to that mutations occurred as a result of radiation exposure.
• The Matrix - The film depicts a future in which reality as perceived by most humans is actually a simulated reality created by sentient machines to pacify and subdue the human population, while their body's heat and electrical activity are used as an energy source. Upon learning this, computer programmer "Neo" is drawn into a rebellion against the machines, involving other people who have been freed from the "dream world" and into reality.
• Terminator 3 - the story unfolds, the T-X coincidentally finds the Resistance leader-to-be.

List of Weak SciFi movies

• Superman
• The Hulk
• Zathura

the weak Scifi movies doesn't have any possibilities and not even likely to happen because it cannot be proven by the scientist and it's only made by a wild imagination of the writer/s.
