The scene at the lobster shack is very well done, all the detectives are seen having a laugh at the absent Pembletons expense. This scene where the detectives are shooting the breeze, eating lobster, is key, and introduces and starts to develop the characters in this premiere episode.
Bolander can be heard repeating "Detective Munch" at various times in the episode, this is done to give Munch confidence and it works. Munch pulls an allnighter, working on a dead end case. Bolander's words rub off and Munch can later be heard uttering the same words "Detective Munch". Munch's hard work pays off as he notices something odd in an old booking photo, leading to a suspect.
You get the sense right off the bat that Bayliss isnt much of a people person, mistaking Crosetti for Giardello. Bayliss is put into action right away, gaining some tips from the experienced, conceited Pembleton. Bayliss isn't afraid to take a stand even though he is still wet behind the ears, as he questions how ethical Pembletons interviewing tactics are.
Overall this is a great opening episode and does a good job introducing the characters, but at the same timekeeping the viewer entertained with four cases.
