How do I watch canon Kenshin content?
You're gonna want to watch Trust &amp; Betrayal, then Reflection.  While the ending is not what the author wanted, its still semi-canon and good.  It also covers some of the final arc (Jinchuu Arc) at the end of ova 1 and beginning of ova 2.  Also the fight animations and soundtrack are great. Also worth watching if for nothing else than the reinvented fights (which are more realistic) is Rurouni Kenshin: New Kyoto Arc.

Then I would go back and read the manga after where Trust &amp; Betrayal left off, it covers a lot of details that really add to the story and overall depth to characters (like sanosuke's past)
