If you're looking at this item you're probably looking because you've seen the series on TV and maybe wondering why it's only down as 2 1/2 stars - hence, you won't be paying attention to the numpty's that insist on writing a bad review because it's NOT their favourite show.
If you're looking to buy the complete series, I'd hold on a little longer as they usually release the complete series a couple of months after releasing them in parts 1 and 2. This will obviously be because the show airs later in the UK and they won't want the ending being too well known via DVD before the series has finished on TV.
I won't go into what the show is about as you probably know (and there's a synopsis above from Amazon if you're new to CSI) and will hopefully have seen most of the series on the TV - if you have missed any it won't hurt to invest in these it's been a great series and I'm hoping that Jordja Fox has signed up to do more.
If you are a CSI fan - get reviewing and get those star ratings up!!
