In three words: A character study.
When I saw this movie I didn't had any expectations. If you like explosions, sfx, big plot lines or adventure then this isn't your cup of tea. However, this doesn't mean that this movie is bad. Personally, I think this movie is a welcome change compared to the amount of Hollywood blockbusters that are coming out every month. What I really liked about this movie is the fact that it takes its time, allowing the viewer to think and share the moments of the main character, good and bad.
The focus is on the main character Lachlan MacAldonich, a former Scottish rock band member who immigrated to America because of problems in the past. After living in America for many years, he gets caught drunk driving resulting in deportation. From this point on we follow Lachlan through his struggles caused by the pressure of the present and his burden of the past.
The movie is a character study with a slow pace, so please keep an open mind when watching it. California Solo focuses on the character Lachlan MacAldonich portrayed by Robert Carlyle, who gives a great performance. The supporting cast is reasonable and helps to create the right atmosphere and story progression. However, the movie has its flaws namely, that it is very slow and personally I think certain character interactions didn't work very well.
In the end I give California Solo a 7, because it was a reasonable movie with good acting, emotional content, and a deep submersion of the surroundings.
Recommendation: Watch this movie around 6pm during a sunny day, because the light and timing adds to the atmosphere of the movie.
