Others have given some good information and advice above but here are a few more points.
DSLRs do have a tendency to produce darker pictures. There are a few quick things you can try. Firstly, increase the sensitivity. Somewhere in the menus there is an 'ISO' setting. Increasing it will mean you can take pictures in lower light or use faster shutter speeds but the higher the number, the noisier the image will be. Canon DSLRs are about the best at keeping this noise to a minimum though. Secondly, you can apply exposure compensation. I use a Nikon D70 quite a lot and I often have it set to around +1 EV so that it doesn't underexpose every image I take. Thirdly, its worth mentioning that if you shoot raw instead of jpeg, the amount of adjustment you can make to the brightness of your image afterwards is increased dramatically meaning underexposure becomes less of a problem.
Unless for some reason you paid over the odds that is actually a very good value camera. Not cheap, but great value for what you get certainly.
One other thing you should know. The pictures this camera takes are DARK and fuzzy.

Oh and unlike JFK's camera, mine was NOT a bargain.
