Normally, I would say that a good game could be made regardless of the genre, but I am now of the opinion that there is no such thing as a good isometric platformer, nor will there ever be I suppose.
Let me recount a tale for you. I was searching the Interwebs for a top-down Metroid type game. I saw some folks mention a game called Scurve: Hive. It was a game that strangely launched on both the GBA and Nintendo DS. The game sounded oddly familiar to me, so I opened my box of NDS games and found that I already had a copy that I had apparently found in a bargain bin for $10.
I popped it into my Majora's Mask New 3DS (gotta flash my nerd-cred!) and gave it a go. While I generally like the coloring, enemy design, weapons, and environment, there was one thing that really bothered me that made the game near-unplayable for me.
What does a platforming game consist of? Jumping from platform to platform using precise timing and coordination.
Using precise timing and coordination!
What does the isometric view entail? A camera projection that makes everything the same size regardless of distance or height.
Regardless of distance or height!
What happens when you mix precision jumping with a camera projection that prevents you from judging platform position? You get a terrible game, that's what!
Flash forward a couple months to the current day and I recently got Rare Replay on my Xbox One. Included in the collection are several old isometric platformers from Rare. While I will admit that the use of lighting and shadows in Snake Rattle 'n Roll made it not as frustratingly difficult, others, such as Knight Lore are abysmal.

In summary: Never make an isometric platformer!
