That's almost a conviction. That's almost a condemnation... I remember Harry Potter, which was also served to us in instalments. It was annoying, but also exciting. No, I can't say that the wait spoilt my enjoyment of the books, nor that of my children. I had a similar experience with Diana Gabaldon or Rebecca Gable...

Luckily, I started reading Harry Potter when Deathly Hallows was published. Otherwise, I would have gone nuts. Especially when everything is interconnected with some explanation throughout the series. If I had to wait like you did, I think I would have reread the previous books if I had to. Yes, I would have been annoyed, but it doesn't hurt to make exceptions for a masterpiece.
