Sure it's a blockbuster movie that isn't meant to be taken super seriously. But Armageddon is actually a pretty decent movie in its own right. The acting is good with very big names, the set designs are good, the cgi has aged fine. The story isn't mind blowing, but it tries to at least give some back story on things and setup multiple plots. There's action parts, more serious parts, humorous parts and emotional parts. The pacing is alright and the movie doesn't drag on or skip any of the important beats. The music is very good, with Aerosmith in the lead.
In the negative column we might say the story is predictable and full of cliches. But a lot of those cliches weren't at the time, they were made into cliches by movies as this. Scientific accuracy is nowhere to be found, but would the audience expect to at that point? Would they even care? There's probably some casual racism, but for the 90s it did alright.
People like to shit on older movies like this, but I feel like it's better than a lot of the Marvel and Star Wars slop we've been getting for the past 10+ years.
Special mention to Steve Buscemi, who has only a minor role in this movie, but is acting his heart out. Loved his performance.
