Success! Shortly after my ranting post I went back, after a calm down, for another crack at it.
I connected the nunchuk after so many said it helped them, and aside from a few bad judgement calls (running the wrong way etc, because I dont play or watch tennis so don't have much knowledge on it!) I got a lot better at reading the game, reacting and multi-tasking with the nunchuk stick and the wiimote- it does help a great deal once you get used to it. I won my first set, and at the same time, my first match in exhibition mode. I didn't make it easy - it went to a tie-breaker and the tie-breaker went to the last point, and I won the match 7-6. YEAH!
Since then I've won 3 games, including one against a 4-star player in career mode (still in easy, mind), so I'm very happy that I've fought through the grind and made it past the learning curve, It is very satisfying.
DO buy Grand Slam Tennis :D
