'Children Ruin Everything'

This Canadian series on CW has a simple gist: When couples raise kids while trying to hold to their childless lives, they find that children can ruin everything. For Astrid (Meaghan Rath) and James (Aaron Abrams), mom and dad duties mean they have to shed a good chunk of their happy-go-lucky days and reinvent life around their tykes. But it's not all gloom and doom — the 30-minute episodes have plenty of heart and humor. Debuts 8 p.m. Monday, WUCW, Ch. 23

'Big Brother' special

The reality series that follows a bunch of strangers trying to coexist in an isolated home wired with cameras is turning 25 this year. And CBS is celebrating the silver anniversary with an hourlong special that looks back at showmances, rivalries, secrets and twists, unforgettable houseguests and other highlights and lowlights. Season 25, with Julie Chen Moonves returning as host, debuts on Aug. 2 and so the special will offer a peek into that, too. 8 p.m. Wednesday, WCCO, Ch. 4

Self-deprecation to win friendship is a big part of his limited world in this CW series. Debuts 7 p.m. Monday, WUCW, Ch. 23

The winning pair will be determined on their creativity and the functionality and quality of their project and get $100,000 and, of course, bragging rights. Debuts 8 p.m. Sunday, HGTV
