I will start by saying I'm a massive fan, having watched every season of 24. However, after the extended break following the end of Season 6, I found myself a little uncertain as to whether I was interested in the new series. The pre-season episode, Redemption, was good without being brilliant so it would be fair to say I had my doubts about the show. But as each episode of Season 7 ticked over, and mind-blowing subplots emerged, I found myself absolutely hooked again. Some reviewers have criticised the lack of believability in this series. I'm sure there are plenty of holes if you want to look for them, but for me it comes down to the following crucial elements:
1. Entertainment value
Season 7 never lets up from the get-go. It literally leaves you breathless at the end of each hour, yet desperately anxious for the next episode.
2. Acting quality
Every character is played by a strong actor and they deliver consistently. I've never seen or heard of most of the new actors, but they are outstanding in their roles. I won't ruin the story for others but there is only one person I wasn't looking forward to seeing again but they were at least bearable.
3. Emotional response
This is the first series since Season 2 when I have felt such a range of emotions. Rarely do you feel anything other than shock when main characters bite the dust. However, Season 7 has some genuine tear-inducing moments. This is due to the quality of actors and of course the great script. Which leads me to -
4. Script quality
The writers have delivered a quality script for Season 7. There are some brilliant one-liners and some quality exchanges.
All in all, one of the best 24 seasons ever. Arguably as good as Season 2.
