>>716073995eh thats fair, I personally think those boss fights are shit but they are memorable moments if nothing else
The Jake races and the 100% final boss from 1 is infinitely more enjoyable to me personally
even though Jake isn't a boss until the last stage of the game every time he shows up he's memorable as your rival.
its interesting you found it hard to keep going because of the bosses, the levels were fun and the finale set piece was a breath of fresh air but you didnt get to that from what it sounds like
