I concur with Kevin.
There is nothing wrong with the principles, philosophy, or techniques of aikido, but the training method leaves a lot to be desired (at least if you expect to use it against a noncompliant person).
Don't get me wrong, you should continue practice the fundamentals, but if you want to use it, you'll have to go beyond that.
The following links are videos showing some of the drills we do at our school. They have various restrictions, and are practiced with varying levels of intensity, but they all involve noncompliant partners. And we don't use atemi.
You can do drills like these too. You just have to give yourself permission. If you are interested, send me a private message and I'll give you some ideas on how to structure these drills.
