Level E (2011) IMDb
Numerous alien species are represented on present-day Earth. Humans are unaware of this and protected by interstellar law. One of their protectors is a royal super-genius whose underlings struggle to contain his wicked schemes and do all the actual protecting.
Comedy based in morbid paranormal/UFO/kitsch-SF tropes. It’s basically Men in Black (1997), and was written at the same time, but has a group of aliens instead of people as the informed diplomats and peacekeepers, and much less action. It’s a series of multi-episode arcs: the initial protagonist is only present in the first and last of them. Not very special, but some of the writing is above average.
