I haven't seen those specific films, but I'd say your brain is looking to focus on things the film isn't particularly interested in, if you're having a boredom problem. Not all films are about a narrative drive from A to B. My unsolicited advice is to relax and let the film take you where it wants to go at whatever pace it wants.
There are a lot of films in this bracket that treat pacing and plot much differently than American cinema, both much slower and much faster. It'd be a shame if we eliminated them all because they didn't match our own expectations of how a film "should" move.
That
was, at times, a problem for me in the past. I've learned that lesson though. I say to myself now "this film was made by a professional, they won't lead you into a dead end", and that's enough for me to let go of the reigns. I'm fine with a movie deciding it's time to stop and smell the roses. I think in this case it's more a matter of the quality and effectiveness of each scene, the freshness of the story and ideas (relative to the viewer), and the room for improvement.
I feel like I should say, I'm not just looking to kill off films willy nilly out of spite or just for the sake of imposing my will on the bracket. I'm merely an ardent viewer looking for greatness.
