Vuuzle also has a limited number of genres compared to most streaming apps. You will only find about 10 genres. But it has the main ones such as Action, Comedy, Horror, Sci-fi and Documentaries.
Another thing is that it does have a search button but again you will only search for movies that are available in the app so don’t expect to type Avengers and find it.
Vuuzle is pretty new so maybe that could be the reason for the limited number of movies. Hopefully the devs will expand its library.
