There's so much one could say about Jet and why he's unlikable. He's thin skinned, fake, disrespectful, incompetent, and has a massive ego on top of it all.
What was he doing in between season 1 and season 2? His social media would imply hanging out and partying but his own words were that he was pulling 16+ hour days sleeping in the office working on a terrible season 1 edit, blocking criticism as it rolled out. A lot of those tweets since deleted.
In short, Jet talks big and fails to deliver. If he focused on real improvements instead of vague ideas he'd be better off but instead he keeps it ambiguous and hypes everything well beyond the team's ability. His lofty estimations were reflected in the absurd prices of TTS and fishtoys earlier in season 2.
Anyone who thinks he's doing hard work sitting in a basement for 6 weeks isn't considering the full picture. Jet will get a substantial payout after 6 weeks of hard work, yet he seems to spend more time sending TTS than improving the show. I know plenty of people who would do a 6 week gig with no days off for a decent payout. Some jobs are just that, it's not much of a feat, it sucks in the moment.
It's also apparent that Jet has no qualms about lying to Sam's face. Once, Sam asked if they had been shilling Zipp and Sam's coffee throughout the show and Jet said they make sure the fish do that. This isn't true, they stopped doing it early in the season. Zipp is effectively an inside joke and after thought among fans and the contestants.
Another example is when Sam asked if people liked the karate, Jet said they do but if they don't then they can watch another room in the house, as if there's anything else to watch during karate. Fortunately, Sam seems to have made the executive decision to end karate so maybe realizes Jet's input is wasted.
Finally, when Jimmy was retard-raging and Sam had to head out, he asked Jet if they were good to watch Jimmy for the night, clearly intent on keeping Jimmy around for longer. Jet insisted they always do. Fast forward to Jet cracking jokes with Ben, who was supposed to be watching Jimmy, and Jimmy loudly stating "I'll be right back!" before heading upstairs alone and lunging at Brittany. Jet made zero effort to make sure Jimmy was tard-wrangled and it could have been disastrous.
Jet tells Sam what he thinks Sam wants to hear and that probably has more to do with where he is professionally than his ability.
Should Sam cut Jet loose it'd be clear that Jet gets by purely on the good graces of Sam.
If Jet would learn to shut up and stay out of the spotlight then his image would improve drastically. Focusing on improving his project(s) and seeking genuine feedback would go a long way, too.
