Planet Terror is excellent and original; why don't you like it?
The kids movies are a good chance for him to create work that his whole family can enjoy - I don't personally watch them, but it's a nice sentiment.
The Machete films were entertaining and silly; not my favourites of his, but I still enjoyed them.
And Sin City 2 was simply hindered by the fact the stories weren't as good as those picked in Sin City. The direction was still excellent though, blame Frank Miller for the writing. Regardless, I still thought it was a good movie.
Your arguments are obviously based on opinion, but even then, you've not clarified such an opinion.
Rodriguez deserves respect for choosing his creative independence over money as often as he has; and also more recently for creating one of the best cable channels ever in the El Rey network. He deserves all the chances he's given.
