I used to love the voice, but I gave up watching in week 3

It's just the Format - it's completely screwed. The auditions span half the entire series, with so many acts.
Then they seem to be cut down so quickly, losing half at the battles and half again at the knockouts.
Then we finally get the best of the best and you get 2 live shows. They can't create a successful winner because there's not enough time to connect with the artists unfortunately. It really needs an overhaul.
