>>17698721Universe is the most complete story in Tenchi, so yes. It's a good start. Watch the show and then the first movie and then Tenchi Forever. If you want a little extra, then Ai Tenchi Muyo after Forever. This is what's known as the Negeshi Timeline and is the most popular.
If you want to go on Kajishima's wild ride, that's a whole other story. To sum up:
Masquerade Trilogy (Hentai) > Dual! Parallel Trouble Adventure > Photon: The Idiot Adventures > Spaceship Agga Ruter (Hentai) > Ryo-ohki OVA1 > The Night Before Carnival > Mihoshi Special > Ryo-ohki OVA2 > True Tenchi Muyo! (Manga) > Ryo-ohki OVA3 > Final Confrontations > Ryo-ohki OVA4 > GXP > True Tenchi Muyo! GXP (Light Novel, ongoing) > Tenchi Muyo! GXP Paradise Starting > Tenchi Muyo! GXP Paradise War (Light Novel) > Ryo-ohki OVA5 > War on Geminar
This story still hasn't finished btw, it just keeps going.
Everything else is Non-Canon to either timeline and just for fun like Tenchi in Tokyo, Pretty Sammy, etc.
