Flower bed (spoilers)

I really liked this movie, but some of the plot devices were really messing with my willing suspension of disbelief. For one thing, the whole "I've been possessed by a ghost after being beaten in the haunted hotel" ruse seemed way too elaborate to be realistic.

But most of all, if I had just killed a mid-level criminal enforcer, the last thing I'd do is bury him in the patio in my own house! I mean, Manson Ma was living literally about 30 feet from a graveyard and his girlfriend was out at work all day -- surely there must have been some way for him to bury the corpse where there was no chance she'd dig it up, and then he would have been able to get away with the money and the girl.
