Why do you think Dear Evan Hansen was so widely acclaimed as a play but so widely panned as a film? (spoilers)

I finally got around to watching it purely out of morbid curiosity. It really was as bad as everyone said it was. The casting of Ben Platt as a teenager was hilarious but it was probably the least of the film's problems. It was so fascinatingly bad that I genuinely don't know where to begin with it. I'm not surprised that Jenny Nicholson has an 80-minute breakdown of the movie because there is a LOT to unpack.

What I found so hilarious was the hubris surrounding it. If you read quotes from the people who made the movie, you can tell that they were all 100% certain it would be some kind of modern classic and dominate at the academy awards. They were not at all expecting the movie to bomb and get bad reviews. The only thing I did not agree with was Amy Adams getting a Razzie nomination (which I think was just mean-spirited). The movie had many flaws but she wasn't one of them and she tried her best to make it work.

Why was the play so much more popular if it was basically the same story? It's not like it was written in the sixties and seems dated now. It first premiered on Broadway just a few years ago. I feel like people should have realized right at the start that Evan was just an absolute monster and not sympathetic at all.
