When asking "is an AI too human", it might be good to know how the AI itself was developed. Let's invent a few new terms...
If the AI develops by accident through the use of technology not deliberately arranged to produce a proto-AI, then we might call that one an "Emergent Intelligence" or EI. In a way, this is exactly what you are, as the product of a 4-billion-years-long evolutionary progress. Though, for you (and intelligent aliens) I think we'd call those NIs or Natural Intelligences.
Only if the AI is deliberately engineered from first principles would I then use the AI acronym. If instead someone does a "mind upload" of a human, then whether they keep that intelligence as-is, or modify it to change its personality/values/whatever, we'd call that one a DI maybe (for Duplicated Intelligence).
DIs will of course be very human if unmodified, and even after (naive) modification they will still have many of the personality traits and other qualities of a human.
On the other hand, EIs will behave quite bizarrely... we might not find any equivalent unless or until we find a planet with an alien species on the verge of becoming sapient. Or time travel, and see how the first sapient primates behaved.
Alternatively, it might be that every toddler is a model for how an EI could work. In which case if you were depicting those, you might make them very childlike.
True AIs, on the other hand, will be absurdly inhuman in the first prototypes, and will remain so unless effort is put forth to make them more human (and good luck doing that, since they're already more intelligent and capable than humans, they may decide they don't want to be guided/bred/developed/whatever). This will probably resemble psychopathy at a glance, but I speculate that if anyone can survive the presence of such AIs long enough, they may grow to feel that actual psychopaths are much warmer, friendlier, and human than prototype AIs.
These are, after all, weakly superhuman minds that can develop (and adopt and later abandon) any personality trait they might want to, for any reason. Even personality traits that aren't extant in NIs. Meaning, if they so cared to, they could invent a new personality trait meant to instill levels of horror in humans that aren't currently imaginable... literally pushing every one of our collective buttons when nothing else could previously.
Which raises the question, with such AIs in your employ, why would you need regular ole biological military weapons monsters?
That AI in a robot body is so much more frightening.
