It's weird because yes I do want more but I want more because season 4 felt like a lead up to season 5.
The ending WAS rushed there's no argument you could make to me in good faith that would make me believe otherwise. If it walks like a duck and quacks like a duck then you can call it a chicken all day but everyone who isn't delusional will know it's a duck.
With some of the weird structure of the show I honestly think the show was meant to end in season 3. Which, ok fine, but the thing is it didn't end in season 3, I feel like it should have been possible to make a decent season 4 and the fact that you didn't expect it to continue is only going to take you so far as an excuse.
