Unpopular opinion: I Did not like the movie Rockstar!!

So I've seen the movie like a month ago, and it was actually my 3rd time watching it. Meaning I tried watching it twice but I couldn't get myself to continue it. So I watched it again when it was re-released because everyone was going gaga over it. My main issue was Nargis Fakhri's acting; like, whenever she was in the scene, I could do nothing but stare at her lips, like they were very weird. Next was their relationship; I personally found their relationship not impactful enough to feel what the ML felt, which made him write all those songs. Like, it was not impactful; maybe it was because of the FL's acting (god, that was a horrendous sight to witness). But I do love the songs and Ranbir Kapoor's acting. But the plot was weak, and the whole storyline was bad, and obviously the FL's acting. AM I NOT SEEING SOMETHING THAT EVERYONE IS SEEING OR HAS SEEN, WHICH MADE THEM LOVE THE MOVIE!? I AM FUCKING LOST.
