Up All Night has been pretty good throughout. Funny enough that I'd almost probably have watched even absent Arnett. Both show off that they can really act - Arnett as a reasonably convincing normal-person straight man to Applegate and especially Randolph, Applegate as a reasonably convincing semi-dork who does not look like what Applegate looks like. Randolph has backed off the show-stealing antics of season 1 of late which is too bad as she reliably got the best lines. Finally this past episode though Arnett let a little freak fly, *WONDERFUL* *spins ecstatically in circles à la Sound of Music opening* but still within in-character bounds. The nice moment, flashes of GOB, when he guesses that Gene is 45 and can't believe he's 34, and especially his frantic multi-mimicry "bullet points" which brought back both Baldwin's unforgettable role-playing therapy mimicry and, at the end, unmistakable evidence of his friendship with Krasinski (real life, not Jim) in his identical timing and style.
