First, their flashing ad's at the top of the screen are unprofessional. That's low for a major network.
Second, the games they choose to replay are arbitrary. Just have them all available on demand; stop being stingy. I know you're making plenty of money from those poorly done ads.
Third, my stream has died in the beginning of the 2nd half. I've tried multiple browsers and even other games at this point. No dice. And where's the customer support? Non-existent. WatchESPN is miles beyond NBCSN; I hope NBC loses the Premier League contract. They don't deserve it and I for one will not be tolerating their poorly disguised ad app any longer.
Reason of review: Poor customer service.
