I think for most people its not a big deal. For me personally its really annoying, because outside of sports videos I search for a ton of marvel/superhero/geek/videogame videos on youtube. For some reason youtube keeps recommending me hate videos on Captain Marvel. I've seen no more than 30 individual take the time to complain but I haven't actively searched for it.
For those jsut criticising the film on equal footing with every other film than fine. If you have cinematic critiques fine, thats everyone's opinion. But if you're attacking this film because of press conferences videos or Brie Larson's personality or that the movie has a female lead I don't want to hear it. Half the videos complaining about her are misquoting/taking her statements out of context when she was discussing A Wrinke In Time and applying it to other things. Some people have even taken recent press junkets to insinuate she's some kind of terrible or annoying person. All the press junkets have been in good fun like they always are the cast jokes and throws around some sarcasm. I'm very tempted to delete my youtube cookies in the hopes I stop getting these recomendations. People have gone so far to push claims of empty theaters and otehr absurd things which I refuse ot belive without actual evidence. Still I think this is a very small contingent. I'm sure there are a number of people who thought the film was mediocre or might not have cared for it but they don't go out of their way to find ways too belittle the film they just go on about their day.
anyway i digress. I imagine people will keep finding things to complain about until people stop giving them attention and views
