This review may contain spoilers. I can handle the truth.
On the streaming services they try to sell "Kajillionaire" with the genre "Comedy". The title and the film trailer suggest the same thing. But this film is many things, but only about 10% comedy. The rest is mostly Drama, Arthouse and in the end also a wonderful Romance.
So if you want to see a light-footed comedy as I originally wanted, you will be disappointed. But if you want to see a complex, crazy and tender coming-of-age film, watch this work.
