First off I can kind of feel sad that I have missed most of the 'argument'.
From what I have read I <3 you to Ammo
And yes Samurai X is very good, and don't worry Hermoor, there are no schoolgirls, giant robots, mini-skirts or post apocalypses' going on.
There are swords and violence though so if that makes you squeamish I wouldn't recommend watching it.
And make sure to watch the OVA and not the TV series. The OVA had a much higher budget.
As for my favorite animations, story wise would be GITS, F**ked up factor would probably be Paprika, meaning would be Princess Mononoke and thought provoking would a film I believe that was made in germany called 'the perfect man' or something along those lines, I will have to come back with the actual tittle later (as search results are brining me to a really bad looking hollywood movie).
