Observe and Report - Stops being funny

Almost any love scene in a comedy could make this list—MacGruber, American Pie, Knocked Up—because love scenes in comedies are specifically played for awkward laughs, but Observe and Report isn't a standard comedy. It's dark, twisted humor from the creator of Eastbound & Down, so when Seth Rogen finally lands his dream girl, Anna Faris, their love scene strays directly into seedy territory. They try to recover the scene with a joke, as the passed-out Faris with whom Rogen is getting it on half wakes up and says "Why are you stopping?" but at that point the date rapey vibe becomes too much. That's a gross exploitation of a terrible situation. Not to mention just watching a sweaty Seth Rogen fumble his way through love-making with any beautiful actress is tough to watch. It even makes you empathize with Katherine Heigl, and that's no easy task.

Requiem for a Dream - Did that really just happen?

The uncomfortable scene in question here occurs at the end of Requiem for a Dream, when each of the main characters are deep in the worst chapter of addiction. We're literally witnessing their rock bottoms. Jennifer Connelly plays Marion, a heroin addict who resorts to selling her body for the drug when she is recruited into doing a "show" for a bunch of demonic, salivating men who jeer and throw money on her and another woman during the performance. It's not so much a love scene as a horrifically graphic act that occurs amid a swirling, brilliantly edited sequence that not only weaves together the awful predicaments that each character has found themselves in, but also imparts their panic and despair onto the audience through the effective, if not jarring use of shock value.

American Beauty - Your daughter's friend is never okay

Despite the fact that American Beauty is undoubtedly a great movie full of fantastic performances, it doesn't change the fact that one of the storylines involves a dad lusting after his teenage daughter's friend. When Kevin Spacey and Mena Suvari finally have their vomit-inducing love scene (which thankfully stops short of the big moment), the tenderness of Mena's vulnerability only serves to highlight how inappropriate the whole thing was from the start. But throughout the movie, Spacey's lustful fantasies about her are generally played for comedy, so when their real encounter finally happens, it's a very "Please tell us this is not happening right now" moment. The punctuation of the scene where he covers her with a blanket is such a post-traumatic gesture that most viewers are probably just relieved it's over. Plus, he gets murdered moments later.

This scene isn't any easier to watch in a post-MeToo world, where Kevin Spacey has been accused of multiple sexual improprieties, including some involving young people.

Watchmen - Superhero sexy time

Second only to that blue naked guy, the weirdest thing in Watchmen just might be the big sex scene. Nite Owl (Patrick Wilson) and Silk Spectre II (Malin Akerman) join forces for some dirty superhero action. It's celebratory sex after an evening of crime-fighting (and coming right after an unsuccessful tryst where a nervous Nite Owl couldn't, uh, perform his superhero duties). But really, it's about two people who have to put on superhero costumes and beat bad guys to get in the mood. What's really weird is that Nite Owl and Silk Spectre make love in Nite Owl's "Owlship" vehicle to the strains of Leonard Cohen's "Hallelujah," a song that's more sad than sexy. Critic Geoff Boucher of the Los Angeles Times called the scene "off-putting," and we have to agree.
