I actually liked the Karl Urban film, although some of the uniform design was a little different. I think what was done right was the dark and dismal approach to life in the Big Meg and the one-dimensional approach to the plot. Okay, so it was more or less a copy of 'The Raid', but one of the (many) mistakes made by the Stallone movie was trying to cram in as many elements from the comicbook as possible. It turned out as a mess. The newer version kept things simple and managed to stay crisp as a result.
I hope this series follows that same rule, introducing a little of the flavour week by week, without overloading everything. There should be plenty of good plots to choose from and keep it going indefinitely, without even having to write anything new.
