Getting back on topic to IKK though...I have to wonder if the lukewarm/negative reviews are partially because the cast is really young/inexperienced and therefore don't have a ton of exposure to foreigners (at least at first)? Knowing how little knowledge the average Japanese high schooler/undergrad student has, it wouldn't surprise me if a lot of the poor treatment was from lack of worldliness, assumptions (gaijin smell bad, gaijin are rough customers, gaijin are more std-prone, etc) or from stereotypes.
