Looking for a word describing someone who is "too nice" [closed]

"Too nice", as in constantly trying to please others, perhaps motivated by a fear of being disliked, and typically this person is nice or overly excited when others wouldn't be.

Is there a word for this behavior? (That isn't kiss-ass...)

Example use: "I find his ???? personality off-putting."

Thanks!

Solution 1:

unctuous: excessively or ingratiatingly flattering; oily. He seemed anxious to please but not in an unctuous way.

-- Edit -- I had another idea.

glad-handing: The urban dictionary defines glad hand as a "smarmy individual who hugs a lot, gets too close and is generally over friendly in an irritating way." The problem with this is it describes behavior, not personality, as you wanted.
