This movie is so bad i wonder if the 10 star ratings aren't being paid

Rating: 1/10 (21 December 2019)

The one star is for the performance of the main actor. That's it!
I really was expecting an amazing movie according to all the reviews ... but really, it - does - not - make - any - sense.
What in this movie makes it so different that it deserves a 10? On average, users would review that a 6 or an 8 at max.
So i wonder if there hasn't been a scam somewhere telling people: "Put a ravishing review on Joker and you'll get an iPhone for free!"
The movie is very slow, very repetitive, not surprising, dragging, stupid (Joker seems to be 50 while Bruce is 10 ... So when Batman arrives, is he fighting a septuagenarian ???!!!) ... and dare i say, unoriginal ! All in all, boring!
