Well objectively speaking, they've both got loud music, hero worship sequences and unbelievable action sequences (by unbelievable I mean "are you kidding me there's no way that guy did that"). KGF has got the hero taking on 50 people? RRR has got the hero taking on 100 people if not more. But wait, it's also got a guy fending off a tiger on his own. So yes, I simply can put it in the same bracket because both of them, to me, are action movies that don't respect the audience's intelligence.

It's like watching a Fast & Furious movie. You know it's going to be over the top but as long as you enjoy it, it doesn't matter. At least to me.

Hey I'm not a fan of the movie either, which is why I haven't watched the second one. I'm only giving OP what he asked for.

I suppose you could check out KGF. It's got two parts (I haven't seen the second one yet) but the first one has got everything you asked for. History, action, music etc.

It's got a 'guy takes on an army' feel to it.
