The 2008 "Incredible Hulk" movie is definitely science fiction. It features:
* Superhuman abilities: Bruce Banner's transformation into the Hulk, gaining super strength, speed, and durability.
* Genetic manipulation: The origin of the Hulk stems from a gamma ray experiment gone wrong, altering Bruce Banner's DNA.
* Advanced technology: The movie features advanced military technology and the use of gamma radiation.
However, the 1978 "Incredible Hulk" TV series, while still featuring superhero elements, leans more towards action-adventure. While it includes elements of scientific experimentation and genetic manipulation, the focus is more on Bruce Banner's journey as a fugitive and his encounters with various antagonists.
Ultimately, both versions can be categorized as science fiction, but the 2008 movie leans more heavily into the genre due to its more elaborate scientific explanations and technological elements.
