Home Video (VHS, DVD, Blu-ray, 4k)

I would also suggest finding boutique retailer you vibe with. The Criterion Collection is oft cited, but it's not the only game in town. I was looking at what was out there last year and these were a few of the retailers that stood out to me.

Kino Lorber: Similar to Criterion in its seniority (started in 77) and art house focus. However, it seems as though their collection has become fairly diverse over time. I saw a 4k of Ben Affleck's Reindeer Games listed next to a Blu-ray of an Italian film I'd never heard of from the 70s, so who knows what you might find.

Arrow Video: UK based company, seems to operate in the same sort of genre space as Shout Factory in the US, with an emphasis on premium box art and pack in bonuses like posters and other bits and bobs. Runs a 2 for $60 UHD Bundle promo pretty consistently on their website. Seems like it's 2 for £40 on the UK version of the site.

Indicator Films (I swear this used to be its own label, but it seems to have been purchased by an entity called Powerhouse Films Ltd.). Another UK based label, seems to have themes for its offerings. Currently, they categorize their catalog in to Film Noir, Hammer Films, Ray Harryhausem, Mexico, Ozploitation, and Jean Rollin. So, covering a lot of bases there lol.

Severin Films, Vinegar Syndrome, American Genre Film Archive, and many others, specialize in the sort of schlock that gave rise to the Video Nasties, a reference I make having never lived in the UK, nor been alive during the time period that term was originated, so forgive me if I'm off the mark on its usage lol. To greater or lesser degrees these focus on the typical genre trifecta of action-horror-sci fi, with some light toe dipping into erotica, which is something to be aware of if you do your Blu-ray shopping at work, like I tend to do lol. Some boutiques are on a strict "check from home" regimen lol.
