G Gundam:Manly men and women doing awesome things with giant robots.
The series takes place in the future and mostly focuses on a worldwide fighting Tournoment.
Its my favorite Gundam.
Tekkaman Blade:And old Tatsnoko anime that started MANY of the tropes you see in most Mecha anime.
Its a simply, guy uses strange ability to rescue earth from a anian invasion, but it does so much with the story and throws in so much heartbreak and drama its one of my favorite series.
Rurouni Kenshin:A wandering assassin tries to leave his past of killing behind, but it wont go away and he tries to seek redemption while trying to protect those around him from the "Ghosts" of his past.
I absolutely LOVED those series, the manga is still my favorite manga of all time to this day.
Samurai 7:A retelling of the 1954 movie 7 Samurai by Akira Kurosawa, it takes many liberty's with the source but, it turns into a great series.
The Gokusen:The daughter of a Yakuza boss is inheriting the family business, but all she wants to be is a teacher.
So while dealing with family issues she becomes the Math teacher for the local High School's delinquent class.
Hilarity ensues.
Saiyuki(Reload and Gunlock):A retelling of the Chinese poem Journey to the West.
It, like Samurai 7, takes liberty's with the story but turns out to be a great series.
Sword of the Stranger:A young boy trying to elude the army of a local lord hires a wandering swordsman to escort him and his dog to safety at a temple.
Basic story, but as they travel the young boy and the swordsman become close and the swordsman's past is slowly revealed, as is the reason the boy is being perused by the lord AND a group of Chinese ambassadors.
This is a movie but i loved it.
Saw it in a theater and it was a experience.
