As you have probably heard, “Joe Versus the Volcano” (1990) is lousy in many ways. Tom Hanks with a floppy mullet. Schmaltzy and sitcommy throughout (even the end credits, they look like a “Bewitched” ripoff). But it’s also cute and funny at times. Hanks’ mullet. Occasional clever dialogue. Meg Ryan chewing the scenery. Remember, just as a big pile of horse manure can yield a beautiful garden, this movie set the stage for “Sleepless in Seattle,” “You’ve Got Mail,” and, to a lesser extent, “Cast Away.” So the next time someone makes fun of it, don’t reflexively agree. Be kind.
