Many amine endings are like that for me. I'm hooked with fun action, adorable creatures, and badass robots, and then it just derails into endless monologuing.
But watching something when I'm not into it? Sometimes, just so I know what happened in the end. If I like some element of it enough, like the setting or one of the actors. Other times, a wiki plot synopsis will be enough to sate the curiosity. I'm getting better about not forcing myself to finish something I'm just not into.
