In my opinion, film censorship is a good thing.
First of all, not every person respects the age rating a movie has. Most people do not really care about the age rating a movie has if they consider that the film has a good plot and it's worth watching. Furthermore, censorship is important because, as mention previously, underaged people might be watching it, so it is principal that the directors and staff of the movie focus on it and remove the more "inappropriate" parts.
For example, there are a few movies which take into consideration that younger kids might be watching:
De exemple nu stiu, daca stii tu scrie. Poate ai vazut tu vreun film asa.
