First, I really enjoyed the movie. It's probably best Matt Damon's acting class in a long time.
Second, the characters building are pretty good and solid. Matt and the little girl were my favorite.
Third, the culture shock that movie shows is something real. I'm European and lived in the US for 4 years. Texas and California. I lived several funny situations too, mostly in Texas. Great memories.
Last, the script and storyline are simply great. Some little plot holes here and there, but still an amazing work in all aspects.
To add, filming locations were great. Marseille and Stillwater were the perfect combination for filming this drama.
So, ovearall an excellent piece of cinema that includes beautiful bittersweet stories between the characters, great characters building and amazing cinematography. If you're in the mood for that, go on. If not, John Wick's saga could be a good choice if you need action. Either way, enjoy.
