The best way I can think to characterize Showmars is that it's kind of like that girl/guy (maybe an ex) who has evolved into a fairly reliable 11PM hookup when you can't find anything better. The familiarity harbors comfort. The basic need gets satisfied and sometimes it is simply mind-blowing.
But when you're done, you are disappointed, primarily in yourself for poor decision making, and slightly nauseated.
But it gets the job done.
