Pardon me while I defend the title...
All star wars titles have been so-called "B" movie titles inspired by old movie serials. In case you don't know, star wars it's self is partially based on old movie serials as well, hence 6 episodes. Old serials like Buck Rogers and Comando Cody, RocketMan.
The reason people do no like the title, I think, is simply because of the word "Attack", because it reminds them of "Attack of the Killer Tomatoes", "Attack of the 50 Foot Woman", et cetera. No one would be complaining if it were "Assult of the Clones", even though it's almost the exact same.
Notice, however, that it is gramaricly identacal to Return of the Jedi, and sounds no more cheessy then The Empire Strikes Back. Also notice that Attack of the Clones is no worse the Indiana Jones and the Temple of Doom, from the other Lucas series bassed on old pulp fiction and Saturday morning serial pictures.
The following are some of the titles that inspired StarWars, ALL of them.

Lucas is neither stupid nor lazy. If he was, he would not be as obscenley rich as he is.
Do any of you really think that he just said, "Oh, screw it, let's just call it Attack of the Clones...that's good enough." I imagine that there was a long and tedious process that led to this being chosen as the title.
