I've seen Dogma and The Professional. Never seen La Femme Nikita (I assume you're talking about the 1990 movie, and not the late 90's TV series, which I did see a little bit.)
This weekend I tried another "classic" I've never seen, Platoon. I've been on a bit of a kick lately ever since Jaws, trying to go back and watch popular, well-known, or acclaimed movies from before my time. It's quite a different tone and style than the slew of war movies that followed it some ~10ish years later, such as Saving Private Ryan, which it seems that a lot of war movies are still trying to borrow from to this day. However, I thought it held up about as well as a movie from the 80's can. Tom Berenger and Kevin Dillon's characters were truly hate-able and horrifying.
Speaking of, it was interesting to note how many of the actors in that movie are recognizable from other things. Almost everybody in it went on to star in other things, seemed like. Most notably for me, imagine my surprise when Dr. Cox from Scrubs was in a classic war movie.
It took about an hour longer to watch than the actual run time. There was a lot of pausing while my wife recounted stories of veterans she sees (she works for a VA contractor, and Vietnam vets make up a good chunk of her patients). She would see something that reminded her of stories they tell her, or things that she's treated vets for related to Vietnam, and tell me about them. She also can't help herself, when she sees something in a movie like that, she acts as if they're real people and says stuff like "That guy probably died within 20 years from pancreatic cancer" or something like that. But a lot of them won't hardly say anything about their time there and getting info pertinent to their medical claims is like pulling teeth, she says. One of my uncles served in Vietnam, and he's kinda like that. He's not angry, angsty, unstable, bitter, or noticeably messed up.....but he will not talk about Vietnam.
