I see two problems with that site.
1.) Not only are their numbers estimated, they're not sourced, where did that site get those numbers.
2.) How is that anywhere near a fair or comparable chart? Monday night ratings aren't the same as Wednesday aren't the same as Friday. And 7 o'clock is different than 8 o'clock. How can any of that be taken seriously as a metric of popularity?
I mean really, you're just using this as you being pissed that they fucked up the Hulk. You can be pissed about that, but your source is shit.
