Roman barbarians?

[master of the puppets]

i saw this one movie this weekend which was in my opinion an idiotic portrayal of attila the hun and the war with the romans. the thing that truly ticked me off was the battle of chalons in the end of the movie. it showed the romans in full legion regilia, helms, mail, shield, the perfect picture of a legionair. but many have reason to believe that the legionair of the time was not that perfect picture.
Cuts in military costs, lack of income, corruption, had all taken its toll on the army. most legionairs had extremely downgraded weapons and armor, some with only mail. altogether the organization that once made the legion great was in decay.
So it is my belief that the romans could not have been the rich imperial force of old but rather an almost barbarian army, with many hired auxilia and worse technologies.
I merely wish to know the opinions of the rest of you. was Chalons truly a battle of barbarians and the civilized world or a clash of barbaric armies?
