A Dozen Sci-Fi Sequels We Want

From IGN
Does Independence Day need a sequel after 16 years? Producer Dean Devlin seems to think so, mooting one alongside a follow-up to the original Stargate movie.

Some movies though remain begging for that lingering question mark to be answered, left hanging for sequels that never happened.
