Couldn't agree more with Atomicboy, but I do feel some shots are "clunky" to a degree. As stated before these shots add to the theme's rough battle feel.
I think it's funny the Gimli shot is criticized as "rejecting" when the ball flies over. It is meant to be that way, it's a soft shot on purpose and really rewarding if you are able to shoot it consistently. And it fit's the Dwarfs skillset of throwing and catching things with extreme accuracy very well.
The sword ramp feels like a battle sword strike with the clunky target hit on the ramp.
Legolas feels, well, like Legolas, swift and smooth.
PotD is a bit rough and uncontrolled - but again this perfectly fits the movie scenes in the cave when everything breaks down in chaos.
If you want to push it, you could even argue that the Gandalf shot is a bit "wobbly" because Gandalf is an old man.
It seems to me that often players don't even notice how much though went into this game, how every shot fits its character and how the roughness of the theme perfectly translates into gameplay.
Finally, I've owned LotR for approx. 8 months now and have almost made it to Valinor a few times, but I NEVER have had a tower saucer reject, NEVER had any multiple attempts for the Gimli VUK and only had 2 or 3 dropbacks to the tower from the PotD. The Ring shot works very well to, it does drop the ball at mode start maybe 1 out of 10 times, but in DTR it always worked flawlessly in 2-ball-mode up to now.
There is a certain clunkiness to the game, but that is intended and adds to the feel. Everything else mentioned is a problem of the game not being dialed in correctly.
