One of Ingmar Bergman's most well known films, but also looked to be one of his most challenging (on paper at least). Part of that's because of the length. I watched the theatrical cut, which is already about 168 minutes, and there's an extended miniseries cut (which looks like the original version) that's about two hours longer.
I liked this enough to probably give the miniseries a watch at some point, probably somewhere off in the reasonably far future though. The "short" version still felt like a full experience, and went by pretty quick considering its length.
Part of what also made this film look challenging was its subject matter and minimalist style. Being about the breakdown of a marriage and shot in a very simple way, I was worried it would get dull or boring to watch, but it kept me engaged throughout.
It's the acting and writing that really make this as good as it is, and the low-key, simple visuals really help ensure the focus is on the performances and the dialogue. I even found myself liking how stark and static the feel of the film was, as it worked well with the subject matter (a few of those quick zooms didn't look great though, but maybe the effect looked less jarring at the time).
Occasionally there was a line of dialogue that felt a little forced, but that could be as a result of the subtitles filling in gaps, due to the shorter runtime of the theatrical version. But overall, the writing is pretty strong, and I like how it focused on personal issues, thoughts, and feelings, specific to the characters, as I've found in the past that some of the broader, more overtly philosophical Bergman dialogue about "life" and "society" in general doesn't always do it for me.
But in the end, this is one of the best Bergman films I've watched so far, and between this and Smiles of a Summer Night last week, I've been really enjoying diving back into his films. I've only ever seen the theatrical version of Fanny and Alexander, but it remains my favourite film of his, so I may watch the extended miniseries version of that next, to continue this successful run of Bergman films.
