Spaceman Is Quite Disappointing!

So I was watching Netflix's Spaceman, starring Adam Sandler, and it felt quite boring, although I like watching Sandler's movies, however, this one is something that I was not able to watch, I gathered all the energy and watched it for almost 30-45 minutes, but was not able to finish it. All I want to know is if should I go back and watch the whole movie or if there is no need to finish it.
