Thanks for your explanation. I got it.

Only a few characters and scenes made us watch that boring movie.

I am not sure. How can we say it in the correct way?

Only a person can make you watch a movie. Characters and scenes can't do it.

You can say Our boss made us watch that boring movie, but that doesn't have anything to do with your first sentence. Your first sentence (below)

Only a few characters and scenes made the boring movie watchable.

says the only thing about the movie that was worth the trouble to watch was a few characters and a few scenes.

On the other hand, maybe you don't want the two sentences to be related anyway. I don't know how you intend to use the sentences.

Sometimes, I also use that form "Something+Made me+ do something".

Ex: "The wonderful landscape made me stay longer there."

When I use "made me" in that context, I mean "attracted me". I couldn't help but stay there. Does it sound unnatural?

In the OP sentence, he meant the same. The movie originally was boring. The only reason that pushed/motivated/attracted them to watch it was a few characters.
