For a streamed movie, it's very good. The story is very dramatic, the acting and directing top notch. Interesting setting of wine country business details. Not entirely original background story, but gripping enough in its own context. Unusual Tyrol setting, beautiful scenery. The primary actor is very good, the villains are expectably real baddies. A "slow thriller"? - only if you want to binge on Marvel movies, not watch a well done crime drama. Well, everyone to their own taste, as my Irish grandma said about "kissing the cow." You want streamed entertaining diversion? - this is a good choice.
