"Worth it?"
No. I've tried modern Who and 80's Who. It's a children's show. I don't like it
I really wanted to.
To each their own. To my mind, most modern WHO episodes stack up well against any adult American sf series. It can be more whimsical at time, but that's part of the appeal. Who says all sf has to be serious and realistic?
And this is coming from someone whom, to be honest, never really got into the older versions of WHO. (I tried, but those endless serials were just too repetitive and slowly paced.)
"Blink" or "The Girl in the Fireplace" are way too good to be considered just kiddie fare.
