1) “Roswell” season-finale, 8 and 9 p.m., CW. “This is better than a soap opera,” one character says. And longer, too. In these two hours, we get way too many heart-to-heart talks. Individually, each is written and played well; combined, this feel like Dr. Phil has invaded the sci-fi universe. The story mixes aliens with special powers and mere Earthlings without. Most aliens are good, but Mr. Jones is pure evil … and looks like good-guy Max (shown here with Liz, the brainy scientist). That stirs science talk we can’t pretend to understand.
2) “The Big Leap,” 9 p.m., Fox. Nick (Scott Foley) tries to show his daughter how he spotlights personal drama while directing a dance reality show. There’s a lot to find: Mike and Paula get closer … unaware that she’s the auto executive responsible for his lay-off. We see changes for Gabby (a single mom), Justin (her former dance partner) and Monica (the ruthless choreographer). In the noisiest parts of a good hour, Wayne (the bigger-than-life producer) gets entangled in pieces of his past.
3) “Dancing With the Stars,” 8-10 p.m., ABC. This is “Disney Week,” with heroes tonight and villains Tuesday; so far, actor Martin Kove and reality-show figure Christine Chiu (from “Bling Empire”) have been ousted. Also from 8-10 p.m., NBC’s “The Voice” starts its battle round; the advisors are Camila Cabello, Kristin Chenoweth and country’s Jason Aldean and Dierks Bentley.
4) “The Neighborhood,” 8 p.m., CBS. Meg DeLoatch, the showrunner, wanted a realistic look at the days after a miscarriage, something she’s experienced. That part is fairly solid and includes a lovely song by Tichina Arnold. Unfortunately, that story is paired with a witless one about a pimple.
5) ALSO: At 7:45 p.m., Freeform has “Aliens” (1986); writer-director James Cameron turned it into great science-fiction … and one of the best sequels ever. At 10, CBS’ “NCIS: Hawaii” has a good episode, centering on the shooting of a much-liked rancher. And any time, www.acorn.tv has sharp mysteries; arriving today are new episodes of “Midsomer Murders” (a body is discovered during choral rehearsals) and “My Life is Murder” (a clever case is complicated by a habitual liar).
