Films/Shows Featuring Pacifism, Teamwork, Diplomacy, and Maturity?

This might be a bit weird but can anyone recommend films or shows to me that feature as little drama as possible between the main characters? Something that might get at the heart of Stoic or Buddhist philosophy of inner calm.

Like one where a team of people working closely together just get along astoundingly well, never get into drawn-out heated arguments with each other (even in the most trying of circumstances), and mostly just calmly explain their viewpoints (perhaps gently at times, firmly at other times, depending on the situation) and negotiate peacefully with each other.

Star Trek: TNG is the epitome to me but I've watched it to death (all seasons front to back maybe 10 times already).
