Nah, Gripen's a great little bird. Saab knows their stuff when it comes to designing top of the line warplanes, and after its early teething problems (the kind that would make V-22 pilots worry even) it's become one of the premier fighters out there.
It's also one of very few modern designs to have a single engine, which allows it to be smaller, and to be a sight less expensive than neighbors like Rafale, Flanker, Typhoon, etc.- no small consideration for smaller air forces. (I suspect any thoughts Saab may have had about dual-engines were met with flat 'no' replies from the Swedish Air Force, with their accountants holding rolling pins behind them menacingly)
If anything, thanks to its effectiveness vs. bang for the buck, it's surprising that it hasn't had a wider foreign sales opportunity. Particularly with the F-35's continued problems, one would think countries might start kicking the tires on alternatives at this point, Gripen being an excellent choice.
