You often hear film actresses bemoaning the lack of decent female parts. You rarely get that complaint from TV actresses. That’s because they know their medium has reached absolute parity. Their male counterparts have to wade through exactly the same mediocrity they do. Well, this isn’t a particularly good week for TV (except on PBS, which is baiting the trap for another pledge period). But it does contain two movies with unusually strong roles for women—three in the emotional family drama Lucky Day and two in the child-abuse actioner Stop at Nothing.
