Definitely not. Thor Love and Thunder is a multi-faceted movie that incorporates elements beyond just love. It's a blend of heroics, battles, and character development that makes it much more than a simple love story.
The back story of Thor Love and Thunder is complex. Thor has been on a continuous journey of self - discovery. His time with the Guardians of the Galaxy is part of it too. He has seen different cultures and faced various threats. When it comes to Jane Foster, she is battling cancer. Her connection to Thor and her transformation into Mighty Thor is a key aspect. This is all set against the backdrop of a universe where the gods are being hunted by Gorr. Thor has to step up once again, not just as a hero, but also as someone dealing with his past and his love for Jane.
Definitely. The movie incorporates elements and characters from Thor-related comics to create its plot and action. Some scenes and story arcs may have been adapted and reimagined for the big screen, but the comic roots are evident.
