The WestWind Solano Drive-In is showing “Fifty Shades of Grey” next to “The SpongeBob Movie: Sponge Out of Water.”

Parents taking the kiddies to see the SpongeBob movie have to be concerned about this. I mean … who wants their kids exposed to terrible moviemaking at such a young age?

The Bay Area’s CW affiliate KBCW points out that patrons watching “SpongeBob” can look across the parking lot and see all the action happening in “Fifty Shades.”

“That’s not a good thing,” said Joy Peter, who lives nearby at the Dalis Gardens Senior Park and has a clear view of the drive-in. “What do the two have in common?”

Well … many of the SpongeBob characters are mostly naked.

Monica Arias of Pittsburg said she has a 2-year-old who gets fussy, making the drive-in her family’s only option for movies. They went to see the SpongeBob movie Saturday night; her toddler stayed focused on Bikini Bottom, but some older kids on hand may have been more distracted.

“It was weird to see these kids all around though walking to and from the concession stands with the huge butt-naked scenes on the next screen,” Arias said. “There was no way to avoid it, really.”

Neighbor Joanne Gressang told KBCW she doesn’t think the situation is any different from when the drive-in shows other R-rated movies.

“It won’t be the first time,” she said. “I’m sure they’ve had other R-rated movies there on the screens.”

Yeah … but those were probably, you know, real films.

The Hollywood Reporter tried to contact someone from the drive-in without success. A manager there Tuesday night deferred comment to the offices of SyWest Entertainment, the theater’s owner, which did not return calls Tuesday.

By the way, Tuesday night was “Family Night” at the drive-in. That’s an interesting definition of “family.”
