I can respect that. I know plenty of people like this. However, I really think you should give LOTR another chance. There are only two instances that I know of where magic in the spell sense is used in these films. One of those times it was like gusts of wind and it appears Sauroman is beating the bejeesus out of Gandalf with his staff, but he isn't actually touching him. Kind of like how even if a bullet doesn't touch you but gets close enough you feel the force exerted by it. you couldnt see it and the other magic is in the last film and it isn't even in the theatricle cut. Peter Jackson made a strict line that the magic in the films would be subtle and mature and not be showy like you usually see in sword and sorcery films and he didn't cross it. He specifically avoided the Harry Potter type of magic. They don't say spell names either.
Actually there are quite a few instances where Gandalf uses magic, although you are right in that most of them are much more subtle than in the
Harry Potter movies.
The Fellowship Of The Ring
-Gandalf blows a smoke ship through Bilbo's smoke ring.
-Gandalf's fireworks (they're as much works of magic as they are alcemy).
-Gandalf beating Bilbo back to his house after the party (with Bilbo's surprised expression at seeing Gandalf, I'm sure the wizard must have spelled himself there).
-Gandalf's appearing to grow larger and more menacing when Bilbo accuses him of wanting to take The Ring for himself.
-Gandalf's duel with Saroman (obviously).
-Gandalf using a butterfly to send a message to the Lord Of The Eagles.
-The ford coming up and washing away the Ring Wraiths.
-Saruman casting a weather spell to stop the fellowship from crossing the mountain and force them into the mines.
-Gandalf lights the end of his staff in The Mines Of Moria.
-Gandalf's battle with The Balrog.
The Two Towers
-Gandalf disarming Legolas, Gimli, and Aragorn when they mistake him for Saruman.
-Gandalf calling Shadowfax.
-Gandalf forcing Wormtongue to crawl on his belly.
-Gandalf breaking Saruman's spell of control over Theoden.
Return Of The King
-Gandalf defeating Saruman in their brief confrontation.
-Gandalf driving the Ring Wraiths from Farimir and his men as they fall back to Minas Tirith.
-Gandalf's brief confrontation with The Witch King.
(There may be more, those are just the ones I can remember off the top of my head.)
