Wilson Chapman editorSpoiler Alert: Do not read if you haven’t watched “starting now,” the Season 3 finale of “Barry,” now streaming on HBO Max.After three seasons of barely getting away with his many crimes, Barry Berkman (Bill Hader) has finally been caught.Season 3 of Hader and Alec Berg’s increasingly dark comedy series “Barry” ends with the title character — a reluctant hitman whose attempts to avoid the consequences of his actions have caused increasingly greater tragedies — apprehended by a SWAT team, heading to jail for the murder of detective Janice Moss (Paula Newsome). That act, which has hung over the series since Season 1, initially seemed like it would get Barry in jail even sooner, when her boyfriend Gene Cousineau (Henry Winkler) discovered that Barry, his student, was responsible for her death.
