This looks riveting.
I personally found the original "24" to be too complicated with too many things going on with every season. This upcoming spin-off looks pretty basic, it's clearly a cat and mouse action thriller series, it's worth checking out.
A lot of extreme "24" fans oppose this new series, the thing is they're 2 different shows, give it a chance, it has not even aired yet. The original will always overshadow it, but if you like fresh action TV Shows it's worth giving it a chance, whether the original is better or not, it shouldn't cloud your judgement on a spin-off, "24: Legacy" is still keeping the "24" franchise alive.
