I loved the books when I was young. They seem omnipotent but they really weren't.
IIRC, Corwin tried to usurp the throne from his brother Random, and as a punishment had his eyes burned out. Nobody expected he'd regenerate his eyesight, but it did, during years of imprisonment.
Also, what I liked is that they'd all have their own particular skill. Although Corwin handled a sword really well, he could never win against his brother Gérard. He could cast a spell but never as good as his sister Fiona.
There's multiple interesting threads going on. Their power comes from the Pattern (i.e. order), but there's also the Locus (i.e. chaos). There's a court of Amber, but also a court of Chaos. Then there's a whole bunch of family members, who Corwin knows or doesn't know.
However, I don't blame you for finding it a bit boring. We all have particular books and TV series which didn't "click" with us. I mean I found Lord of the Rings entertaining overall, but the writing style extremely long-winded.
