[AoU] is Ultron's strength and power based on how many robots he can produce?

Just saw AoU again and realized he isn't that strong fighting against the avengers individually. Is he a threat because he can produce so many robots and overwhelm the avengers? I have never read the comics.

I think Age of Ultron did a very poor job using Ultron as an AI. The danger of an AI is it will outsmart you. It doesn't have to be faster (but it is, usually) it doesn't have to outnumber you (but since it can replicate, it likely does), it just has to be smarter than you. The movie made Ultron equal in intelligence to Tony Stark and less intelligent than Jarvis. Which is fine for a story, but less impressive when you think about just how dangerous Ultron could have been in the movie. 

His power is based on numbers, but not in a fight. his ability to replicate and his consciousness being able to be transferred to any body makes him more dangerous. If even one Ultron Bot got loose then Ultron survives and is just as dangerous. Had they made him as dangerous as he should be in intelligence and electronics, then he would have been too much for them even then.
