24 - Jack gets in situation, Jack gets out of situation, Jack gets into another situation for the cliff-hanger. Every week.

I'm not saying it's a bad thing, I'm saying that to complain about it is stupid as it is not unique to DIP.
No, the Sweeney was grittier than that. Sometimes the baddies got away.
