I've been saying this since I started watching tennis on TV, it makes it more intense, when you watch tennis with this standard camera angle, you only see the ball going left or right, you can't see the subtle differences between players, it makes the game look too easy, you can't see player's fine movement, ball rotation, and many other things visible from that perspective. Of course, that could be tiring to some people (maybe too intense) so they shouldn't do it all the time, maybe 50-50?
