He wasn't going anywhere in life and took advantage of an opportunity to change that. Wouldn't most people want to better themselves or their situation in some way if they could?
Sure, but that doesn't automatically make them sympathetic or interesting characters to watch. The whole thing was just so totally about his own personal indulgence and advantage, so laser-focused on monetary gain and power as the only important goals in life. I find that shallow and empty.
And I don't remember him blatantly stepping on others to get ahead. He just managed to find trouble.
Again: He ripped off his dead brother-in-law to get a drug hit. That's a deeply selfish and unsympathetic act. The man's bloody corpse was sitting right there and the guy was ransacking his apartment. That's crass and disrespectful to a demented degree. Not to mention that he stole the guy's illegally obtained stash of drug money -- profits from the sale of a drug that was killing people by the dozens -- and used it to get ahead. He didn't just "manage to find trouble." He stole a drug dealer's blood money and used it to benefit himself.
Not to mention that, implicitly, by stealing Vern's stash, he caused the death of Atwood, the billionaire that the assassin turned out to be working for. We learned from Anna Friel's character that abruptly stopping the drug rather than easing off was fatal. The assassin was hunting Eddie to get the stash of pills, and the assassin turned out to be working for Atwood. Therefore, Vern must've been Atwood's supplier, and by stealing Vern's stash, Eddie forced Atwood to go cold turkey, which must have led to his coma and death. So Eddie effectively killed Atwood.
(Not to mention that it was extremely obvious that Atwood was using NZT the moment Robert De Niro mentioned that he'd come out of nowhere and had a meteoric rise to success, yet the script made our supposedly superintelligent lead character too stupid to see that. Another case of the script cheating to make the plot work.)
Sleeping with his landlord's wife wasn't right but I didn't see any blatant attempts at manipulation otherwise. Presumably with his newfound confidence, he simply turned her on and got better at attracting other women. As for Abbie's character, he seemed to care about her as much as any boyfriend or ex would. I didn't see anything unusual there.
It's not so much about how much
he cared as how much the screenwriter and director cared. The movie itself treated its female characters like conquests and complications for the male lead, which is a perennial problem in Hollywood. I should note that the film fails the Bechdel test; the only parameter it meets is that there's more than one named female character, but I can't remember any instance of two of them having a conversation with each other.
The drug hadn't been approved but that's a minor legal technicality.
I think you're misremembering the plot. The drug was
killing people or putting them in comas. It was highly deadly and there was no way in hell it would ever have been approved.
As for searching the apartment while his brother-in-law was dead, it's a movie where you want him to find the pills.
Speak for yourself. I don't want to root for a guy who'd ransack the apartment of a dead ex-relative just to get a drug fix.
His run of success started practically the day after he reported his brother-in-law's murder. The police detective clearly felt there were unsettled questions. The cops should've been following his activities, noted that this guy who couldn't pay the rent before was suddenly buying expensive suits almost immediately after his brother-in-law's death, and started asking some very probing questions. Instead, the detective was just forgotten as Morra spent weeks playing around with the benefits of the drug.
Again, real life. Investigations don't always pan out.
Oh, come on. That obviously doesn't apply here. Eddie wasn't trying to hide his activities. They were public and blatant. It would've been ridiculously easy for the police to notice that Eddie started living large almost immediately after the murder, and that the brother-in-law's stash of drugs and money was not present in the apartment. There's no way the cops wouldn't have liked him for the murder. Yet there was no sign that they were watching him when he went on to do things like taking out a loan from a mobster. And why did the script even bother to have the detective say "Something doesn't feel right here" if there was no intention to have him follow up on Vern's murder, if he was going to disappear completely from the story until the socialite's murder? That's just bad writing.
