A 24 series is never the same without Jack Bauer, which is why after a ratings decline, FOX had decided to can 24: Legacy. The series which featured Corey Hawkins in the lead drew disappointing numbers throughout its 12-episode run.
The limited series featured characters from the 24 series such as Tony Almeida (Carlos Bernard) but unfortunately it did not resonate well with fans of the original series. However this doesn’t mean that 24 is dead in the water as FOX is looking to reboot the series sometime down the road.
However the fact remains, 24: Legacy likely suffered due to the fact the ticking clock format based around terrorism plots could be too 9/11 oriented for today’s fans. Plus without franchise star, Kiefer Sutherland as Jack Bauer, any 24 series like 24: Legacy could be doomed before it even airs.
