Being a trial patient for a new drug myself, I certainly could relate to the premise. Fortunately - for me! - things didn't get out of hand as it did for these poor guys - or not yet, that is!
The film starts off very realistic and well substantiated. They offer more than enough time for us to get to know and like the characters before the mayhem starts, so we can root for them. It is lighthearted at first, and fast-paced. I enjoyed the different characterizations. There's also an interesting reversal of attitude among the characters.
'Bloodwork' turns uncomfortable real quick and you might want to watch some of the scenes through parted fingers, knees up to the chin! Believe me, it gets under your skin. During the final act, things spin out of control at a rapid pace. There's also a few surprises in store. Be prepared, the film becomes rather brutal, gory and bloody.
The actors does an incredible job and I also found the script very good.
Would I watch it again? Yes.
