Do people really think "Purple Rain" is a bad movie? Well, that's what everyone has been saying online for all these years. It does bring up a good question — are there terrible films with spectacular soundtracks? Great pieces of music that still couldn't salvage an underwhelming film?

Of course there are. Here's a look at films whose great soundtracks would be better released as concept albums, or the very least could've used a better film to begin with.

'Tron: Legacy' (2010)

Monocultures began fracturing, thanks to the internet, in the 2000s. Radio hits became less frequent in an age of iTunes playlists, and everyone stopped buying the same albums. But, even now, it's hard to think of a bigger and more successful group than Daft Punk when it comes to universal approval and breaking those barriers. At some point in time, on the dance floor or otherwise, they've had at least one catchy song you've grooved to. Admit it.

So, when Disney decided to make a sequel to the incredibly niche and nerdy "Tron" story, they picked the perfect French men to play DJs in the movie, and make its soundtrack. Unfortunately, "Tron: Legacy" wasn't great. It was vapid and predictable. We get it, there's people inside of the computer, and they wear cool neon, what else is there to say?

'Jonah Hex' (2010)

The DC comic book turned big screen adaptation is horrible and incredibly forgettable — unless you listen to heavy metal. If that's the case, this movie might have made — or will make — quite the impression on you. The score was composed by Marco Beltrami, who has quite the filmography under his belt, but he was also helped out by Mastodon, an Atlanta heavy metal band, who for my money is easily one of the best in the business.

You won't find a better string of metal albums than Mastodon's early work, simultaneously the sharpest and sludgiest hard rock to hit record stores since Metallica's "The Black Album" and Megadeth's "Countdown to Extinction" in the '90s. A genius score wasted on a very bad sci-fi Western.

'Space Jam' (1996)

"Space Jam" was monumental to fashion, music and pop culture. The soundtrack was iconic — "I Believe I Can Fly," "Fly Like An Eagle, ""Basketball Jones" — the music videos were hits, and then Coolio, LL Cool J, Method Man, Busta Rhymes, D'Angelo, Salt-N-Pepa and Jay-Z did their thing. Dig deeper and you'll even find remixes of Quad City DJ's "Space Jam" songs.

Then there's the movie itself. It's bad, but definitely not the worst thing ever made. There are some good jokes here and there but, otherwise, it's no "Who Framed Roger Rabbit?"

'Batman Forever' (1995) and 'Batman & Robin' (1997)

These two Joel Schumacher bombs might be the winner for biggest disparity between the quality of a film overall and its soundtrack. Call it camp, schlock or so bad it's good, the two follow-ups to Tim Burton and Michael Keaton's Batman movies are filled with bad acting and bad writing, but had two redeeming factors: costume-design, and, of course, the soundtrack.

It's hard to come after Danny Elfman's perfect score and a Prince soundtrack from the 1989 original, but "Batman Forever" is iconic in its own right. There was Seal's number one hit "Kiss from a Rose," which stayed on as one of the biggest songs in the world for a good while, as well as U2's "Hold Me, Thrill Me, Kiss Me, Kill Me" which also charted. Add in some bangers from Brandy, PJ Harvey, Massive Attack and the Flaming Lips, and you got yourself a hell of an album to listen to.

The sequel, "Batman & Robin," was even worse somehow — but the soundtrack stayed incredible! How did they pull that off? Smashing Pumpkins provided an A and B-side track, and the Goo Goo Dolls and R.E.M. didn't deserve to contribute to a Batman movie this silly and unserious. You even had Bone Thugs-n-Harmony and Jewel too. Easily the best thing to come out of this disaster of a project.

'Yesterday' (2019)

This movie is fine, not that bad, but you can't seriously use the entire Beatles catalog and have a bunch of jabronis play their music. Ed Sheeran? Get out of here. It's like listening to ABBA songs in "Mamma Mia." The music is phenomenal, but the people singing it are not doing a great job. Stop butchering good music with bad covers!

What about other films? What does the internet think about flop films with awesome music?

• The three most common films mentioned when it comes to bad movies with a great soundtrack are "The Bodyguard," "Purple Rain" and "Saturday Night Fever."

• Movies that aren't very popular, but still have waded into this discussion include "Dead Presidents," "Cocktail," "Above the Rim" and "A Life Less Ordinary."

• A recent trend, demonstrated by two movies — "Suicide Squad" and "The Strangers: Prey at Night" — illustrate how people were tricked into watching the film because of its marketing music; especially its trailers. Great song choices, but better heard as a playlist instead.
