This is set in the future when the sun is dying out. 8 astronauts then have to go to the sun to deliver a stellar bomb in hopes of re-starting the sun. But the mission proves to be increasingly difficult.
I wasn't a fan at first but this has grown on me a lot. This is a very entertaining movie. It will keep you on the edge of your seat from beginning to end. What I like about it is that it kept me engaged all throughout it. Every single one of its action sequences keeps you on the edge of your seats the entire time. The sacrifices made by the crew members are heroic and jaw-dropping. Every characters death scene is handled with care and is done superbly. The movie handles its scenes with care to make them look as good as possible. The movie has a lot of repeat watchability due to this and it adds a whole lot to this movie.
I know that a lot of people complained about Pinbacker, but I disagree with you all. The movie needed something big to spice things up. It needed something to raise tension. Otherwise, the movie would've just been bland. Pinbacker brought a lot of tension to the movie and he carried it with excellence. I know that it's a drastic change of plot so I can understand why someone might not like it. However, what you have to admit is that Pinbacker was a lot better than most slasher/horror movies nowadays. Also, the final third had moving scenes too. Mays death was an amazing scene, the Capa's jump scene is tense and well-done, and the last 5 minutes is just downright beautiful.
This is a really underrated movie. It deserves much more praise. I think that this is a masterpiece. I've seen a few good arguments people have been bringing up but they don't affect my opinion of this. This is one of my favorite movies of all time.
