In retrospect I can see how the PS1 Tenchu games seem janky as fuck but you have to remember this was sort of the developmental stage for stealth games. MGS1 came out around the same time and while it was revolutionary its controls were stiff, too and it didn't exactly have super advanced AI either.
At the time, the game being kid of clunky was less important than the fact that it was a 3D ninja game where you did real ninja shit. You grappled to rooftops, you shot people with blowguns, you lurked around corners to stab unsuspecting fools, you poisoned people, you threw shirukens at people, and while it had the usual cheesy voice acting and dialogue for games of that era that actually worked perfectly because the cutscenes played out like all the terrible ninja movies we knew and loved. All its flaws were very forgivable because there was really nothing else to compare it to unfavorably. The graling hook mechanic in particular made it feel really unique. There just weren't a lot of games where you got to move like that. It was like the rough draft for Batman's grappling hook in the Arkham games.
