Lego prices

I’ve always loved Lego and understand that Lego can be very pricy at times. But I feel like Ninjago has much higher prices than any other Lego titles considering what comes in the sets.
It just feels like a lot of the sets aren’t worth the price being paid for even when compared to other brands prices.
Is this a real thing? And if so why?
If not, I must be over reacting or I’m not quite comprehending what comes in the sets.
