They both have similar directing styles of choppy cuts that zoom-in, and off-center closeups. Their eccentric off-beat storyline ans characters are fun to get to know. IBWGP is more silly, but both stories have their own charm.

Both have a good plot that is psychologically intriguing. While not very similar in terms of execution, type of plot, etc., both are still dark and engrossing plots.
