This movie is bad in so many ways; bland characters, confusing/uninteresting plot that is not detailed, bad narrative, etc

I saw in for the first time this year. It scared me so badly I couldn't sleep. Plus I fell asleep at parts because it was boring.

DEFINITELY the worst of these. It doesn't even feel like a Disney movie! It's creepy, the characters are likeable but not very memorable in my opinion, it has no songs, and the plot is not that captivating. Its animation is fairly nice though and it has some interesting special effects and (some) good voice actors.

I think Black Cauldron is better than this... yeah, Black Cauldron's plot could be executed better but at least it actually has a plot which is more than can be said for Sword in the Stone, which has little to no plot at all. Most of the movie just consists of filler scenes.

^ True. Just watched it this week, and is for sure Walt Disney's weakest film. It's a bit better than The Black Cauldron, at least to me

I always thought this movie was really boring.

Easily. The plot is confusing and just makes no sense, they do a bunch of stuff that doesn't go with the plot at all in search of whatever it is, Taran is annoying, the entire movie is just not very good.
I personally like The Sword in the Stone.
