I agree with you entirely except your line should read "Seriously,
Dinorama is awful and has always been awful and no amount of "theming" can change that."
Dinoland when it first opened was awesome, with one of the most complete, coherent and fully-realized backstories ever. It all made sense and it all worked together. If you haven't seen it, seek out the bulletin board across from the entrance to the Boneyard playground. It has a map of the land as it originally existed, and a lot of awesome details that bring everything together.
But then they added Dinorama and it brought the entire land down with it... And while I admit that the Imagineers did an incredible job getting Dinorama to look authentic to the backstory (cracked and faded parking lot and all), it was a horrible choice of a backstory to be given to work with...
I often think of the quote by someone from WDI (and I can never remember if it was Joe Rohde or Marty Sklar) in reference to Dinorama: "This could all be gone in a week..."
