I don't think there's anything shallow about watching the TV - it's not all mindless rubbish, it can be very educational too - for kids as well as adults.
For example, at 2 yrs old my ds2 can count to five in Spanish, can say hello, goodbye, open, close, up, down, delicious and numerous other things in Spanish - all courtesy of Dora the Explorer.
And what's wrong with slobbing out every now and then to watch something purely for entertainment value?
TV has it's uses but it's very easy to turn it off and go out if you think you are using too much of it.
Entirely your decision of course - not being critical - just hate the way TV is portrayed as 'the devils work'!!
