The show starts out strong but admittedly falters a bit after the first two episodes. Fortunately, starting with the episode about Jim's priest going on the Jimmy Fallon show, it really takes off. By the end of the series, some of the running gags, themes, etc. come full circle and are brought to an awesome and hilarious conclusion in the finale.
I think the finale alone, which is a brilliant parody of It's a Wonderful Life, is worth watching this show. If you are a fan of Jim Gaffigan's various stand up shows released by Comedy Central, you will love this.
Not only is this show funny, but the way it deals with some weighty issues such as family, marriage, and religion are very intelligent and thoughtful, always managing to show both the highs and lows but with the assurance that it will all end happily ever after.
