Donkey Kong Jr. feels like the one that's easy to pick on. Maybe it depends on the person but as someone who likes to watch people do Youtube videos on old games, I usually see this one not praised much.

I can totally see why though, if there's one thing DK Jr. suffers from is the fact that the levels aren't too creative and have a path you usually always go through. I will say the mechanics for the game are pretty good and a great way to differentiate from the first game.

Despite some of the hate I've seen, I still enjoy it. In fact I'd say I like it more then the first DK game on the Famicom. I think a big reason for it is because this game's port actually keeps all four levels which makes it feel more complete to me. I've also just always felt more satisfied playing this one. The vine movement is pretty good and it's way better then Mario's slow ladder climbing.

Of the three launch games of the Famicom, this has to be my favorite. While it's barely higher then the original DK game for me, it's still a game I rather replay to get a high score for if I was given the chance. It's a shame Junior wouldn't find too much success after this game. He's only in like four other games on the top of my head and three of them are spinoffs.
