"Alpha House" (Amazon). Yonder comes the first fruit of Amazon Studios' semi-innovative pilot derby, upon which I reported and opined at length last spring — see here , here and here — marking its arrival as a producer of original streaming content alongside Netflix and Hulu. Of the eight contending comedies offered for public inspection (of which "Betas," a Silicon Valley sitcom, has also "gone to series"), it was clearly the heavyweight, with a script by "Doonesbury" cartoonist Garry Trudeau, cameos from Bill Murray (cursing) and Stephen Colbert (wrestling), and John Goodman in a starring role as one of four Republican senators sharing a cramped townhouse.
