Not good. This movie was... not good. There was absolutely no character development. Adam was a pretty guy honestly and for as much as she protested, Katie certainly didn't feel bad enough about their actions to ever actually stop going along with very shady things.
There were a lot of plot points that didn't make sense and weren't wrapped up. If Mr Calvern cared about the reputation of his company, he wouldn't have shown up at the house in the middle of the night for no apparent reason. Julia would've known as a lawyer, that representing Leonard, Katie, AND Adam was a massive conflict of interest. Where did all of that money in the attic come from??? Why was toxicology testing not done on Leonard? If the police were actually looking into his death, why did they not take his medications and medication log as evidence? How is Katie going to pay the massive amount of property taxes on that giant house? 100,000 dollars is not going to cover expenses for very long. Thinking about all of this during a 1.5 hour movie is exhausting.
