You just watched a movie and you hated everything about it. You thought the acting sucked, the characters sucked, the dialogue sucked, and the movie completely unfulfilled any kind of viewing pleasure. Now, you have to give the film maker notes.
Would you mention the bad acting, bad characters and dialogue, or would you just trash the story and forget about everything else?
First of all, welcome back
Secondly, I see a lot of films like this and I usually end up trashing the story or the need of the filmmaker to make the "great South African film": my story to the filmmaker is that (a) they should learn to write a better script and (b) that great film was made long ago.
