Stupid is a strong word, but I think that you should definitely play it. Not only is it a great game in its own right, it gets the humour right, and there's still some fun platforming and exploration to be had in the hub world, even if you don't like the vehicle challenges. You already know it's not a traditional platformer, just approach it with different expectations, and you might find it entertaining.
Right. Remember when the next 3D platforming Rayman was announced, with actual gameplay footage being shown, and then the game turned into a Rabbids party game? Some people were disappointed, but the game never got anywhere near the same amount of hate that Nuts & Bolts did. The same is true for Viva Pinata: Party Animals, fans of the original don't hate that game, they just ignore it. There are numerous other examples.
The game could do with an X patch, but the performance problems were fixed ages ago, the BC version runs perfectly fine now.
Thanks, maybe I'll give it another look next year.
