I actually only saw it for the first time a few weeks ago. It's okay, honestly it seems like a fanfiction that Disney decided to animate into a movie
I don't consider the whole thing canon by any means, and while there were some scenes that annoyed me, other times I found myself laughing way too hard.
Actually, I remember when I was a little kid, I saw the "Digga Tunnah" scene at my cousin's house...whether someone was watching the movie, it was a preview on something else or it just happened to be on the screen, I'll never know. I just remember watching the scene, never having even heard of
The Lion King back then, and that song has stuck with me ever since. Who knew one day I would discover that was a foreshadowing to my TLK obsession.
Anyway, I don't take all of 1 1/2 as canon, it feels like a totally different story to me, but at the same time it's very funny and I accept it as a comedic take on the original. Not really my style, but that's just my opinion. (Plus, since the whole thing is told from Timon's perspective, I have no problem believing that he may have exaggerated
just a bit to make himself the hero of the story.)
Honestly, the line "We're gonna get old walking across this thing," just makes the whole movie for me.
