4.5 Weakest series JPMurtagh | 04/07/2010 | See all JPMurtagh's reviews (33) Undoubtedly the weakest series of 24 out of the eight but still decent enough television. Series was 5 was possibly the best but the writers definitely had a bad day at the office with this. The explanation of the sinister characters at the end of season 5 are laughable as it turns out that Jacks brother and father were involved in the assassination of David Palmer. Rediculous idea but once you get about half way and you stop laughing at how silly that is the last half improves. Thankfully season 7 returns to form.
