One movie that could potentially fit this theme is 'Life'. It involves an alien life form that has a rather complex and somewhat parasitic relationship with the human characters, though the 'love' aspect is more in the sense of the struggle and connection between the two species. Another could be 'Slither' which has a parasitic alien entity that takes over a small town. There are some underlying themes that could be related to a strange form of 'love' in the way the aliens interact with their hosts.
I'm not sure if there are many movies that directly have an 'alien parasite love story' as a main theme. However, in some science - fiction shows like 'Doctor Who', there might be episodes where there are alien parasites and some form of relationship that could be interpreted as a love story. For example, the Doctor often has to deal with strange alien species that might have a parasitic nature and the relationships he forms with them or those around them could be seen in that light.
A possible plot could be that an alien parasite enters a human host. At first, the host is terrified and tries to fight it off. But as time passes, the parasite starts to understand the host's emotions and the host begins to realize that the parasite has its own consciousness. They gradually form a bond and fall in love. For example, they might start to protect each other from other threats, both from within the human world and from the alien parasite's original species.
Well, 'Life' is also a parasite - related science fiction movie. It's about a martian life form that is brought back to Earth's space station and turns out to be a very dangerous parasite. The movie builds a lot of tension as the astronauts struggle to contain this alien parasite.
There might not be a very well - known book exactly named 'alien orthodox love story'. But in the 'Ender's Game' series, there are elements that could be related. The relationship between Ender and the alien species he encounters later in the series can be seen as a form of unique connection that might be a bit like an 'alien love story' in a broad sense. It's more about understanding and co - existence which could be considered as a different kind of 'love' between species.
There's 'A Bronx Tale'. It tells a story where a young boy is caught between his working - class father and a local gangster. The boy also experiences a form of love story that is influenced by the gangster - filled environment he grows up in. This movie really shows how love can be shaped by the tough surroundings of the gangster world.
I'm not aware of many mainstream movies specifically with this theme as it's quite a niche and often not in the realm of typical family - friendly or widely - accepted concepts. However, in general science fiction, movies like 'Avatar' has elements of inter - species relationships which could be loosely related in terms of different species interacting in a profound way.
Another interesting one is 'Roswell High' book series. It's set in a town where there are alien - human hybrids and there are several love stories that unfold between humans and these special beings. It delves into the challenges and the beauty of such relationships.
One popular 'alien anime love story' is 'Tokyo Ghoul'. Although the ghouls can be considered as a kind of 'alien' in the context of the human world. The relationship between Kaneki and Touka is complex and has elements of love. They are from different 'worlds' in a sense, with Kaneki being a half - ghoul and Touka a full - ghoul, and their journey together shows a form of love story.
Another one might be 'Atonement'. There are scenes involving soldiers and a complex love story. The film beautifully weaves the story of the lovers against the backdrop of the war and how the actions of different characters are affected by their feelings and the war situation. It's a really moving story that shows the power of love and the harshness of war.
Another one could be 'Life After Beth'. In this movie, a young man's girlfriend Beth comes back from the dead as a zombie. It explores their relationship in this strange new situation where she is no longer fully human but he still has feelings for her. It has some comical elements along with the love story aspect.
Sure. 'Spider - Man: Into the Spider - Verse' has elements of a love story within the superhero plot. Miles Morales has a budding relationship with Gwen Stacy which adds an interesting dynamic to the story. Another one is 'Wonder Woman' where there is a romantic undertone between Diana and Steve Trevor. Their relationship is a key part of the movie as Steve helps Diana understand the world of men while Diana shows Steve a world of superhuman abilities.
