I honestly was expecting to give this movie at least 7 out of 10 mainly because I rarely ever watch anything 'black comedy'.  I'm not being biased at all but this was really enjoyable and I loved every bit of it, especially after the 20-minute mark. It started off a bit slow for me but then it gradually built up and I couldn't stop watching in one sitting without pausing. It has a tiny bit of suspense and it's quite hilarious as well. Violent scenes are not severe/graphic.

If you're still contemplating on whether or not to watch it, just try it out. If it's boring for you once you reach 20-30 minutes in, then it's definitely not your cup of tea.
