According to 247°F, the movie is "based on true events." It seems that’s meant to refer to people generally locking themselves in saunas, because the characters don't feel like real individuals. Take Jenna, for example; we are told she's "cute ... smart and interesting and fun.” These seem like descriptions applied by someone else (since Scout Taylor-Compton plays her, I’d question the “cute” part), as are Ian’s (Travis Van Winkle) supposed qualifications: a physics major, an English degree, and a communications minor. Ian claims he has "always had a fascination with literature," and "always loved to write;" however, when discussing the Sauna of Doom, which Wade (Tyler Mane) constructed, Ian refers to it as Wade’s "latest and most recent installment." He certainly knows how to phrase things, doesn't he? However, Ian does make an accurate observation when he notes that Renee (Christina Ulloa) is dominant in her relationship with Michael (Michael Copon) — earlier, we see the two of them supposedly having sex; he’s bare from the waist up, but she’s wearing a shirt and pants. That must be uncomfortable. Regardless, it could be argued that being confined to a small space while scantily clad isn't the ideal setting to showcase your intelligence or personality (though for the audience’s sake, perhaps it is); I would counter that Spanish drama Madrid, 1987 — whose characters are writers who sound like it, even when naked in a bathroom — might disagree. In 247°F, there's also the issue of intense heat, but while that could excuse you from being clever and engaging, does it justify disregarding logic and reason? For instance: when Wade’s dog Beau starts barking near the sauna, Ian, Jenna, and Renee try to talk to him; here, Ulloa is forced to deliver (and repeat) the awkward line "Please, God. Let us out, Beau." Seriously, you realize it's a dog, right? Why are you praying to it? It’s not holding you captive any more than it can free you — or do you expect Beau to suddenly grow opposable thumbs and open the sauna door? Perhaps a little zoology would be helpful next time, yeah?
