Maybe you got a bad unit, but it seems more likely that you are not compatible with an automated manual transmission. Perhaps you would be happier in a Corolla, Civic, or if you wanted a near relative of the Focus the Mazda 3 as they all have torque converter backed planetary automatic transmissions.
Personally I don't prefer the lossy torque converter in this size/ class of automobile (The C-segment aka compact). You might even like the 2.0L Dart, but not the 1.4L as the multi-air turbo automatic is another DCT, possibly another Getrag unit.
The DCT has been perfectly responsive for me, but I'm aware that my car was built with the latest programming, but even the older programming on the 4/11 built rental I had back in November likely had the original programming and I never noticed anything terrible about it, it was unobtrusive and was mimicking a mixture of a regular automatic and a manual, but it was the best of both worlds, not the worst as you seem to have experienced. 17k miles on a rental car and the transmission shifted perfectly and it even got really good mileage (>35.x mpg even though I'd gone faster than 75-80 for at least 50 + of the 180 miles in the day I had the car.
