I haven't seen Law and Order, but I have seen boston legal, all of them, and the first season of Lawyers. My feeling is that boston legal is better, and he is also realistic, sharp and profound. What is valuable is that it can make you feel happy sometimes, cause thinking sometimes, and be eager to know the follow-up. The true colors of lawyers is very old. No matter the quality or the case, at least the first few episodes of the first season are not very attractive for the time being, but they may be attracted if they continue to watch, because boston legal may not feel so excited if he only watches the first few episodes, so he must watch the first and second seasons, and he will feel better and better after watching them one by one.
Moreover, it is said that many law professors will use the play in class, because there are a lot of wonderful court debates, which are very authentic.
You can try it yourself, and you won't know if it's your own dish until you see it.
