I don't mind watching doubles sometimes. The Bryan brothers are really fun to watch. It's just a completely different game than singles. I think most of the strategy in doubles happens before the point even starts, where as singles it's easier to see how a player sets up the strategy during the point. Don't get me wrong though, ATP Singles is way better.
One way to make it more enjoyable to watch would be to have announcers that actually follow the doubles tour. Right now, I don't even know most of the doubles teams. I think it could be really neat if you had someone explain doubles team strategies, and good/bad tendencies of each player/team. In general, I doubt doubles will ever get that popular, but I think Tennis Channel could really promote it. I'd rather watch a Bryans doubles match than Destination Tennis. Tennis channel could even run replays from this year's Bryan brothers aussie open. You still wouldn't watch it?
