What a year for TV so far — the first half of 2015 has already given us a motherlode of great screen moments. So here's a breakdown of this year's best shows so far. Some are deserved hits, some are acclaimed artistic achievements, some are totally slept-on gems still ripe for discovery. There are brash rookies and crafty veterans. There are larger-than-life characters, from Cookie to Louie, Dany to Taystee. This year's prime television treasures come from all over the map: stoner comedies, hip-hop soap operas, wigs-and-stockings period dramas, sci-fi spoofs, superheroes, killers, geeks and jailbirds and dragons and spies. It's time to do the Peggy Olson hangover strut down the hallways of 2015.
