It seems to me they were conflicted. Ultron seemed menacing, but that shyt felt hollow.
And indeed, he should've been waaaaaayyyy more menacing than how he was portrayed on film. The whole film itself had a lot of issues.
Yup. And Whedon is the first to talk about them but as someone pointed out, he's quick to point out the faults of his projects and blame them on someone else and not his writing or his own shortcomings.
