A TV Pilot logline that I hope is good!

"A disgruntled middle-aged mercenary fights bandits and demons for gold while dealing with his heroic and super friendly brother, a greedy lordess and her narcissistic son, the goofy members of the local fighter's guild, and a host of fantastic troubles."

*Edit - After reading the comments I think I've thought up of a much better logline.

"After his heroic brother is killed during one of his many quests, a grumpy middle aged mercenary must take care of his nephew while dealing with demons, bandits, and the eccentric townsfolk trying to help him raise the child."

A question though, would a mockumentary style show work for this premise? The idea is basically fantasy Parks and Rec/The Office kind of mockumentary show but I'm not sure if people would question that type of show if its fantasy.
