Parts of it remind me a lot of the black mirror episode where a person's upload is trapped in a "cookie" to do menial task automation. Particularly the part where an upload can be run a multiples of hundreds, or thousands of times real world wall clock time for "conditioning".
Not fully virtual, though. Just the badly maimed torso and head of a victim of a terrorist attack on a train, brain wired to systems, stimulating the last working remains to replay the last 8 minutes over and over again. To gather information and reconstruct 'whodunnit'.
A lot of the early episodes were really stomaches turning, and that's what made the series special. It started in the very first episode with an absolutely disgusting scenario that, none the less, was nearly 100% believable in how every step of its ridiculousness went down.
It wasn't stomach turning because of the pig thing, it was stomach turning because we knew, deep down, that we were exactly who it depicted us as.
