Too much time, someone has (not you).
I don't think we should judge DRS on what happened at the sphincter of the universe. I'm not sure if you'd say they got it wrong because I'm not sure what the alternative was (DRS on the front straight instead, perhaps?), but the back straight just gave too much advantage to the passing car. At the end of the day, though, I'd rather see easy, even bogus, overtakes than none at all, because then the faster driver has a fighting chance at using his car's speed.
I admit that DRS + KERS does make F1 a bit Mario Kart, though. That's not going to change unless the FIA can figure out how to make the cars less aero-efficient and -dependent. They've tried, but they haven't quite managed it yet.
More grip than power = boring racing. More power than grip = awesome racing.
So what's the solution? MOAR POWAH!
