Did I miss something or this movie doesn't have any purpose?

Do people just call this a masterpiece just for the sake of it?

I've seen old movies like Clockwork Orange that people consider "weird" and liked it and even find this one weirder than that! And the only reason I'm giving a 6 and not a 5 is because of De Niro's acting.

With all the "masterpiece", "such a great film" "revolutionary masterpiece of a film" I heard about it I was expecting to be blown away by the story and dialogue, but there's near to no story here other than an incel's journey to being a hero!

The dialogue is bafflingly bad and empty, I was expecting great dialogue from this one but it's just not there. Just go and watch the scene with Travis talking to the other taxi driver on the street and see what I mean. It's a 5 minute of nothing. The whole dialogue is "well I mean.... It's just.... I mean.... well.... yeah.... you know...". Like what!?

The interaction of characters with each other is just awkward.

The movie is also a little boring, and don't use that word about movies lightly because I've seen a handful of long movies with stretched scenes and long dialogue scenes and wasn't boring for me but this one is just on another level.

And what was that ending? Is Travis supposed to be the hero now? Really?

What an utter disappointment this movie was, all these years hearing about it and thinking it's one of the classics and then finally watching it like this...
