Energetic and physical to play, but no real nuance or tactical variation
The other problem is that unlike the very good Wii Sports tennis, there's no reality in your swing dynamics. You *must* swing before the ball even gets on your side, so it just doesn't feel right or realistic. Also, if you play real table tennis, the 6 swing directions are clunky and again nothing like real forehand/backhand swing dynamics. The 6 swing directions just "aim" the ball instead of actually imparting the spin that would be applied if you swing like that. You must also exaggerate your swing quite a bit... there's no nuance for soft shots or drop shots. There's no feel of slamming the topspin, or chopping or pushing or any of that.
It's like the difference between Wii Sports Golf and Super Swing Golf. Super Swing Golf has a very realistic feel to drives, chipping, and even putting, and reads your slice/hook based on whether your open or close your face at the point of impact, just like in real golf. But Wii Sports Golf is a mess and doesn't feel realistic in any way. By comparison, Wii Sports Tennis actually feels mostly realistic and responds like swinging a real tennis racket. But Rockstar Table Tennis feels completely disconnected like Wii Sports Golf.
