It's clear from the last season 9 that love is not blind. You need to get extremely irresistably desirable men and woman which love is blind has not been able to do very well this time.
Also, I feel the contestants are not really in love, just infatuated and going along the ride since netflix is paying for their luxury. as soon as the luxury comes to an end, the breakup happens.
There is nothing new inspite of doing 9 seasons. Its time for love is blind to end and for Netflix to invest their money in new and more engaging material.
