>lack of actual discussion on a topic and there's only arguments about taste and whatnot
Are you talking about 4chan /film/ thread or here? This board used to be more active on it's original site 8chan, before 8chan (now 8kun) was shut down multiple times. You can see there are a lot of topics archived on the 8kun board. You're free to repost them here to discuss as you wish.
This board is a small bunch of people who likes cinema, you can talk about any film here, even Transformers if you have a point. Though we tend to focus on lesser known films, we're not elitist.
4chan /film/ contains too much shitposting and autism for me. Here we just want normal, civil discussion.
