I would say the French Open is the least exciting to watch out of all the tennis championships. Around this time I feel that players are gearing themselves up for Wimbledon and don't want to cause unnecessary injury and if they are there they don't commit themselves to a full match no matter how this will effect their world ranking.

The most grueling tournament to win in all of tennis. Especially on the men's side, the quality of play normally far exceeds that of Wimbledon, particularly because each point must be much more strategically constructed, due to the slow red clay playing surface. Thus, simply belting out 150 mph serves alone will not surfice to win this great championship. Indeed, a champion of Roland Garros needs, amongst other traits, an incredibly high level of stamina, grit, finesse, patience, creativity and heart. As others have already mentioned, the French fans are also highly involved in the matches, and are rarely shy in expressing either their teeming admiration for a player and his/her performance, or at times, intense dislike. Ergo, the colorful crowd behavior of the French adds an additional dimension to this Grand Slam championship, particularly in contrast to the reserved, and at times, far-too-polite audiance at Wimbledon three weeks after.

Boooooring.

The French crowds really get into their tennis and that's part of the fun of watching it. Also, we get a chance to see some players we usually don't get to see because american television almost always runs their players right into the ground until you are sick of them. That's alright at this tournament, because usually after the first three of four days all the americans are gone (at least on the men's side). Another thing is the court conditions. Clay courts allow for longer rallies and the big servers usually have to hit some real shots to win.

Clay court tennis is probably the most exciting to watch. The surface slows the ball down, so there are fewer aces off of serves, and rallies last longer. This is probably my favorite of all the terniments to watch.
