'Avengers: Doomsday' trailer has been getting criticism over poor CGI, with fans comparing it to films like 'Ramayana' and 'The Odyssey'. An X user wrote, "Ramayana glimpse visuals dominating Doomsday visuals after being criticised so much is insane." Another wrote, "You don't really appreciate how practical Nolan went with The Odyssey...until you see something like the trailer for Doomsday."
