While I LOVE the pilot, there are many negative points just as mentioned by you guys:
* cheap CGI (but only for a few seconds)
* the short runtime (would not have hurt, to give a little more scenes to Amanda, Pablo and Kelly)
* Ash's creepy loser character
* the dumb reason for the demons to return
The last two points are my biggest problem with the episode and I want to go in detail about them, because they would have been so easy to correct.
To begin with Ash's character you have to keep in mind, that there is no consistence characterization in the movie series either. EDI-Ash only exists in this film as a whiny college student. In the reboot, that EDII more or less was, he is a goofy average Joe, who deeply loves his girlfriend and goes insane after the events of her dead, until he adapts a more masculine, but also grim and tragic hero attitude with a clear sign of technical skills (chainsaw-hand). In AoD then he is that arrogant asskicker who mainly aims for selfish goals and shows signs of unbelievable stupidity but also incredible technical knowledge (mechanical hand, DIY-gun powder, deathcoaster etc.). At this point, his characterization already went off tracks and Sam Raimi himself admitted that in comparison to EDII. That leaves us with the fact, that there is not one single Ash character, when you see EDII-AoD as one plot entity.
What should they have do with it when creating AvED? In my opinion: Not turn the douchebag/idiot-meter from AoD up to 11.
As a writer I would have tried to bring Ash emotional evolution from EDII and AoD in balance. You could explain his behaviour in AoD as a form of extreme frustration. He lost his girl, his hand, his mind through pure terror and is now stucked in the past with primitives, who want to kill you. I can "understand" that after all of this he goes "screw you! I will insult these apes, bang their hottest chick and ride back home". In the course of the story, he finds his bravery and courage from the time, he helped Anne Knowby, back and he returns to his time as a hero. This is his state of mind/character, when he is back home.
Question is: What kind of guy is he 30 years later?
In my ideal version he suffers from post-traumatic disorder aswell. But after AoD he might also suffer from the loss of his hero role. Of course he tells no one about the things happening in the cabin. And maybe he even has to keep low-profile, because it is still a mystery for the authorities how his friends/linda disappeared while on vacation with Ash. In my version our hero is also deeply frustrated for living in a trailer and still working as a stockboy, because in the movies, we saw, that he has impressive engineering skills, that could have land him a much better job in all these years, if not his state of his mind was so damaged. So he still goes to bars late at night, drinks down the terrible memories and maybe, while drunk, he might even mumbles the truth to some teens like Pablo and Kelly, who think that he is a creepy lunatic.
There could still be a female barfly who ask about his hand. And he could still tell her the story of the rescued boy, but not impress her but just to have a explanation, that is less strange than "evil went into my hand". After telling that, he could still see, how impressed she is, think "meh, if she really wants" and still bang her, but without the silly lothario-act behind it. So in my version, I could use the same story tropes, but tune them a little bit down, for a more realistic approach.
For the return of the deadites I would have two alternatives in mind:
*Version A is quite near to the real product: Ash has a date in his trailer who loves poetry. But he does not show her the book or even reads from it. She might find it on her own, while he gets her a drink. "what the hell is this?" she asks. "Nothing!" and he rapidly puts it away. Then they still smoke some weed. But in my version Ash falls asleep while drunk and his date search again for the book, thinking it might be his dairy or something else personal. Then she reads the notes from Prof. Knowby aloud ALONE, not with Ash, how has to know much better! After he sees the first deadite at the bar, he could still find some clue like the weed bag later. So you would not have to change the structure of the episode at all.
*Version B would be quite different. In short: Ash is a paranoid and alcoholic mad man, who is raged by all these people, who don't belive the stories, he tells late night at the bar. The hero from the past is insulted by the kids as a aging loser. So he thinks "Loser? I show you what kind of loser I am...". So in secret he uses the book on purpose to unleash the dead and, after people are terrorized, he saves them in somekind of lunatic scheme to impress them, to show them the hero, he was and still is...until the dangers become bigger as he tought. That would shift Ashs role from hero to villan in some degree, but it would be a interesting character development, I think (more interesting than dump pothead at least), and at the end of the season he could still redeem himself as the hero, he was meant to be.
So what do you think?
