I find them samey because of the number of powers directed solely at combat. In OD&D very few spells are combat-related. Sleep at first level, then Fireball and Lightning bolt at 3rd; most deal with out of combat situations. Furthermore, Clerical and MU spells are utilitarian in very different aspects of the game. MU spells deal more with trickery, while clerical spells heal (cure disease) and help make new potential allies (speak with animals). Clerics have very few combat-focused spells at all.
Inside of combat, 4e characters are very different from one another. I agree, but I find all characters focus mainly on one aspect the game: fighting.
That being said, I'm an OD&D guy. I play with 3 main classes. I don't have huge problem with similarity.
Nitpicking:
I would say that Charm Person is an attack spell. It is very powerful in OD&D :
«Charm Person: This spell applies to all two-legged, generally mammalian figures near to or less than man-size, excluding all monsters in the “Undead” class but including Sprites, Pixies, Nixies, Kobolds, Goblins, Orcs, Hobgoblins and Gnolls. If the spell is successful it will cause the charmed entity to come completely under the influence of the Magic-User until such time as the “charm” is dispelled (Dispel Magic). Range: 12”.»
Also, you can make an Anti-Cleric if you choose Chaos as an alignement. Many cleric spells were reversible and became attack spells.
