The issue is though the MCU connected so strongly with audiences across the globe and becoming the defining franchise of the 2010s.
Like you may not feel there is a coherent voice but anyone who watched Iron Man 1 in 2008 to Endgame saw the character go on a crazy arc which in the middle seemed confused and odd but it all came full circle and as a result his death really hit hard to people.
So yeah you could say the MCU sort of got lost sometimes trying to tell a coherent voice (would say Ultron phase when the MCU was really confused).
However unlike so many finales that failed so badly this decade, star wars, game of thrones and many more...
IW and Endgame told a pretty coherent story that really resonated and solidified the MCU with an epic conclusion putting everything together.
So you guys can keep calling the MCU films tv shows, but that is what people want in film and TV now.
