Good: 

24MP APS-C CMOS Sensor.
3 Inch monitor.
Affordable.
Sharp images.
Great relation between price and performance.
Full HD video capture.

Bad: 

No Wi-fi.
Continuous shooting mode at 5fps could be improved.
Flash is a little bit erratic.
1/4000 shutter speed could be improved.
Needs more manual controls.

Bottom line:

The super affordable Nikon D3300 gives you superb quality images, semi-pro video recording capabilities, and is a great beginner camera for someone who wants to go into the DSLR world.
