Very disappointing

Rating: 2/10 (7 October 2018)

When I had the opportunity to watch this movie, I jumped at the opportunity since it has an exceptional reputation. But I found the movie thoroughly disappointing and I regret even watching it.
One of the first things that stood out is the movie is extremely long and drawn out. Many scenes drag on showing boring unimportant details for ridiculous amounts of time.
I was relieved when the long and boring introduction finished and the dialogue began. Unfortunately, the dialogue was short-lived and few and far between for the rest of the movie.
I spent most of the movie straining to find an interesting, logical plot, but the plot was minimal and not engaging. Some aspects were also vague and disjointed. What little plot that was shown was drowned out in the boring filler content that comprised most of the movie.
A number of the scenes depicting space-related concepts are interesting from a scientific point of view, in the same way that watching photos and videos released by NASA might be. But this isn't what I was looking for coming into the movie; I wanted something engaging and entertaining.
Lastly, the ending of the movie was terrible. It was drawn out and over-the-top while also being extremely vague and confusing. Completely unsatisfying.
I spent the entire movie waiting for it to "start" and get interesting, but it never did. Not recommended.
In hindsight, I suspect the movie is popular because it was relevant and novel when it was released 50 years ago while also making a realistic depiction of some aspects of space.
