However many Terminators are unveiled, the mechanical heart and soul of the series will always be Arnold Schwarzenegger’s T-800. He’s the android version of earlier, cast-aside operating systems: a Game Boy with a gun. “I’m old, not obsolete,” he says in “Genisys.” And that, surprisingly, is the case. Schwarzenegger’s return to his most iconic role provides much of the appeal of this otherwise purposeless redo.

What’s most refreshing about “Inside Out” is its inversion of the standard prescriptions of big-budget animation: It’s ultimately about the importance of embracing sadness. This, you may have noticed, isn’t exactly the conventional moral one generally finds at the multiplex.
