My all time favourite ten (in order):
1: Close Encounters of the Third Kind.
2: Firefly / Serenity
3: Taken (the series by Speilberg, not the film by the same name).
4: Doctor Who (any)
5: Star Wars (all of them)
6: Star Trek (any)
7: Matrix (all of them)
8: Terminator (first three)
9: Stargate (SG1)
10: Goodnight Sweetheart (comedy about a time traveller - very funny)
The list has many many more. I just love Sci-Fi
