Ben Affleck does NOT look good -- but at least he's home for Father's Day!

The Oscar winner returned to Los Angeles from out of the country looking worse for wear on Sunday. The Batman star arrived solo, wearing a blue bomber jacket -- maybe he didn't get the message about the SoCal heat. But the dude looks pretty sweaty, so it seems like he's feeling his fashion faux pas!

While his face looked super tan, he also looked very tired. The actor may have been weary but he still graciously signed autographs for his many fans.

What a guy!

We have a feeling that Affleck was heading back from his international travel to be with his three children, Seraphina, Violet and Samuel. He may not have been a good husband -- but he's definitely a good day!
