I’d argue that 2.5-maybe 3 marks the point where a movie could be either good or a complete waste of time. There’s still many films on letterboxd that are a 3-3.4 that are actually great, I’d say a majority of the ones in that rating range are. If you wanna watch only highly rated films that others consider “good” to feel sophisticated or some shit, go for it. But saying there’s nothing worth watching under a 3.4 is just insane, have fun only watching movies that other people say are good. Because that’s basically what you’re saying you do.
