I find it a quite bizarre show in terms of narrative structure or whatever. The first 3 were quite dull and clichéd, i thought,then it kind of took off in number 4 when one of the guys went under cover, kind of climaxed in the next one and has been drifting on since then. Like a soap opera but with furious people. i'm on number 7 or 8 now and am just sticking with it to see what, if anything, is going to happen.
A bit like life in that way.
