These are extremely well done episodes and especially well acted. However, if you've seen the US version of Law and Order, the episodes will be very familiar because these are all adaptations of the original Law and Order series that ran in the US for 20 seasons. Obviously some situations and/or elements have been changed to suit the UK but the main story is the same. It doesn't make the show weaker but a certain amount of deja vu takes place for fans of the original who have watched and rewatched the older episodes.
