1) “Dawn” finale, 8-10 p.m., Lifetime. The first three movies (rerunning at 2, 4 and 6 p.m.) battered Dawn emotionally. Now she has actually found joy – a warm husband, a sweet-16 daughter Christie (shown here) and a comfy estate. This, of course, must change. The final film offers tragedy, then propels Christie to New York and to the eerie plantation where she was born. Surrounded by relatives who are berserk, even by soap standards, she gropes for a normal life.
2) “Saturday Night Live,” 11:29 p.m., NBC. When “SNL” has a stand-up comedian host, it usually gets a bonus – a smart, audience-tested opening monolog. That’s been true of John Mullaney and Zach Galifianakis … and the host of tonight’s rerun, Amy Schumer. It was her third time hosting and Steve Lacy was the music guest.
3) “Shark Week” finale, Discovery. The annual marathon has its final new hours at 8 p.m. (following up on reports of 14-foot mako sharks off the coast of Portugal) and 9 (elusive great whites spotted by some South Australian fishermen). They’re surrounded by reruns, to 4 p.m. Sunday.
4) “Shakespeare & Hathaway,” 7 p.m. ET, Ovation. In England, this was the opener for the second season; in the U.S., all the seasons run back-to-back on Saturdays. This hour – about the disappearance of a dog who inherited a fortune – is goofy, sort of fun and surprisingly benign … so much so that you might almost think it’s Canadian. A second episode follows at 8.
5) ALSO: “Greatest Geek Year Ever: 1982” wraps its four -week run with an hour that includes TV people making triumphant jumps to movies – Eddie Murphy in “48 HRS.,” Ron Howard, Henry Winkler and Shelley Long as the director and stars of “Night Shift.” Then again, if youy want to relive a great movie, switch to HBO for “Shakespeare in Love” (1998) at 5:50 p.m. and “Good Will Hunting” (1997) at 8.
