Absolute Nonsense 24 was and will remain to be one the best TV shows. The thrill, excitement, and emotion that Kiefer Sutherland brought to the screen was a class apart. This show, however, does not do justice to its predecessor.
The acting was mediocre, if you're going to bring back a classic, the cast should match up to the expectations.
Also, 24 got its name from 24 episodes depicting 24 hours of the day. If you're going for a revival, why make only 12 episodes like in 24: Live Another Day. Why couldn't they have 24 episodes? It's just stupid to make the 12th episode of 13 hours.
The twists and turns that made 24 what it is were just not there.
Overall they did a decent job but were no match to the original one and that's why it probably got canceled.
