> moviechat is OK for old movies with old discussions

MC still has active discussions on new releases e.g. https://moviechat.org/tt1341338/Good-Luck-Have-Fun-Dont-Die.

They even have a forum for computer games: https://moviechat.org/bd0000053/Video-Games

It's a pity that MC and TMDB boards didn't become the equivalent of 'HN for visual media' and Reddit for the wider 'audience'. Today, Reddit is possibly the most popular site to read non-mainstream reviews.
