@Alphaphlare; Did you honestly expect the movies to be good? I certainly didn't. The point of the episode wasn't the movies themselves, it was making the movies. But hey, it was better than their last one. And of course it's amateurish - it's a theme park built into a film studio. They aren't going to give their big budget stuff to kids. As for the pacing, I never once believed that was the entire film - that they were only showing highlights for the sake of the time slot of the actual episode (so in-universe, the audience would have seen the entire film).
Are you seriously questioning how Luke could have his knowledge of films at such an age in a show where ten year olds are allowed to travel entire regions on their own by foot for the purpose of capturing Pokémon and making them fight for sport?. We know nothing of Luke's history - maybe he has a parent or older relative in the industry? You never know. We also know nothing of the Pokémon World's education system.
Also, it was never stated when Ash saw "The Dirty Herdier". It could have been during his Unova adventures, but off screen. As for Ash not caring at first - he's always been that way. If he's in a town or city with a gym, he's always wanted to go there right away. He relented because both Cilan and Iris wanted to go to Pokéwood; he's also thinking of his friends as well as himself.
I think you need to take a step back and stop over-analysing the show. It's light entertainment for children - and the added knowledge about green screens and acting techniques that were demonstrated in it are pretty educational (and the green screens are also a reference to the feature in Black 2/White 2, which has you battling a green screen during Pokéwood).
