A lot of it's predictable but Jeff Bridges & Karen Allen are great
I thought I knew all of John Carpenter’s films but apparently I didn’t when I found out about Starman. It’s not like any other movie he made. That’s because it’s an alien romance as Jeff Bridges is an alien who takes on the form of Karen Allen’s dead husband. The two have to adapt to each other but then predictably she falls for him. There’s a good bit of comedy thrown in with common tropes about aliens not understanding Earth customs and language. There’s also the theme of the government seeing aliens as a threat. While those are very predictable it was still an enjoyable movie. Bridges and Allen both give strong performances and that’s really the reason to watch the movie.
