There are barely any movies that depict anything about AI or the Singularity realistically at all. The only one I can think of that is even remotely plausible in recent years is Her. A couple of classic ones are so abstract that they stay OK because of the lack of details - the last act of 2001 and the the last act of Contact are probably the only decent ones.

Everything else is entertaining, but garbage as far as realism goes. Star Trek, Ex Machina, Terminator, all that stuff - fun, but complete nonsense.
