What do you guys really think about this movie?

i watched this recently.. and can’t really understand what was so great about rajkumar rao saving her from the case she got falsely accused of? it was shown dramatically how his mom sold her jewellery to pay the money back to kirti’s parents but didn’t her parents do the same for the dowry? there’s nothing personal or wrong kirti did with rajkumar while she, was instead made false promises and her parents were being harassed for money. i don’t understand how is rajkumar taking revenge justified in any way?
