The "problem" with Nigeria is that it is a very densely populated country, and the first part of the country that you will see when you arrive is Lagos, which is one of the most densely populated cities on this earth.
In those two respects, the country is really no different from other countries/cities that have huge, tightly packed populations - think of New York, Los Angeles, Paris, etc. They are all a bit overwhelming until you get used to the lay of the land and the local customs. What tends to make things a bit worse (for expats) in Nigeria is that unless we are of African ancestry, we stick out like a sore thumb. If any one of us went walking around in New York, LA, or Paris wearing a T-shirt that said "tourist" on the front and back in 12 inch high letters, well, it would feel like Nigeria.
