At first you don't succeed just keep trying though!!!

This is a very awesome game on the Wii, easily the best tennis game i ever played since you pretty much control everything that happens. By all means the motions are not perfect and its not 1:1 all the time but most of the time it delivers how it should. WM+ is a good addition and i have been pretty accurate on the court with my shots because of it. I will admit the first 5 hours i was frustrated how this game just didn't seem to work for me, but i kept at it and eventually it just all came together. If you play it by turning your hips like you would on the court the shots come out pretty right (you have to make sure where you have the remote and how you swing it as well). Now i am a pro and just lighting up the game and having a blast, a good workout as my right shoulder is just plain sore and have started learning to play left handed because i am that addicted to how it just seems to work so well on the screen from what i am doing in my living room. Whether you are casual or hardcore its a great game with pretty good amount of things in the game. Hopefully when they make the 2nd one they will add tons more players and venues to play in. Just remember it wont come easy right in the beginning but if you make an effort to learn and pay attention to how it all works(practice court a lot) you will start to enjoy this addictive tennis game.
