What are the negatives to buying a home theater projector?

Projectors are great. Many do not own a cablegram tuner, so you shall need to have an external device like a cable box to melody your TV channels. The bulbs are a bit expensive. As the another person said, you need to be more careful with room lighting. There should be extremely little light on your screen surface. If you fix the legroom up right, projectors can provide a hugely impressive image for not too much money.
