GodzillaFan1990's wrote:B-bu-but Stump. First movie was a big hit and box office success. Wouldn't people not be blinded by that to not notice? Also possibility of making him different from his novel counterpart as with many MCU counterparts from their comic ones (Star-Lord being an 80's pop culture loving junkie).
Same reason for Rocket and Groot due to movies being big hits and box office successes as well as association with Marvel/MCU.
Rocket and Groot have so much more going for them besides being Marvel characters. If you strip the MCU aspect from them both you're left with two highly expressive humanoid-like characters who are portrayed by Bradly Cooper who had a strong following already from the Hangover movies, and Vin Diesel who has a huge fandom anyway, two widely loved actors playing comic-relief characters who appeal to a mass audience for being cute and funny.
To argue why general audience would favor that over a foreign flying turtle monster is ridiculous and just sounds out of touch. GOTG and Gamera are in no way comparable. Find a new crutch to lean on cause yours is broken
