Grin. I used to be in general practice in a medium sized city. It wasn't boring but I'm doing something else now and am much happier. I did it for a dozen years and really made a difference in the lives of clients and for that I am grateful. I also worked so hard I had to almost die (literally) before I noticed anything was wrong. The problem is that you're dealing with contentious people, all day, every day.
I also dealt with people accused of some pretty heinous crimes but, on the whole, they were at least straightforward criminals. When I read the first thread on this movie, I thought, "These guys have obviously never met a client who knows he'll lose his house and his wife and his business if he gives you that piece of paper he just found." Sometimes, part of your job might be to talk someone whose back is against the wall into doing something that is completely irrational to their self-interest and whole way of doing business. And then you might have to explain why their death really ISN"T preferable to dishonor. I think the movie made it look really easy to hire a hitman but I have no doubt that *many* clients would hide that paper.
In my very first criminal defense, we won even though the prosecutor lied, cheated (via evading the rules of discovery), AND stole (sent an agent to try to get a piece of what they hoped would be physical evidence) and they did it with a clean conscience because they really believed they were on the side of the angels. It's common knowledge that "Insurance defense attorneys eat their young." Whenever you see a courthouse shooting, it's not because someone lost money; it's always because of custody and divorce.
Aside from that, it's pretty cool. I don't know. Sometimes it's the most fun you can have with your clothes on. There is *nothing* like feeling a jury go with you when you're making your point. Helping an innocent man go free or getting kids placed with the right parent or seeing someone open a business that you helped them start: it's Good Stuff. It's just that you almost can't want anything else. What did K say in _Men In Black_: "If you're strong enough?"
