The Hulk has always been about smashing stuff and outlandish foes and the like. I always liked the period where Hulk was often in other dimensions and worlds and the like. But there is also the story of Banner and his struggles to keep the beast under control and the series did a good job with that. I understand the desire to have the former but I wouldn't say the series didn't have anything in common with its source material. And we did get to see Hulk smash but his power levels were scaled differently.
