I'm not understanding the hate this show is getting. I get that the show probably didn't go where a lot of people thought it would, being a sort of continuation of the 2011 movie "Limitless" but honestly, the way people seem to think it should of gone is boring in my opinion. Every show out there seems to be full of heavy content and really dark, and this show, while still having some heavy themes, is like watching the show equivalent of a rainbow. And I love that! It's light, it's funny, it's well-cast (despite what people say about the lead, who, IMO, is the best part of the show) and it doesn't need to go in a darker, more intricate direction. I mean, also consider that as I write this, the season is only half done, and there's plenty time for more political intrigue or whatever people seem to think this show is lacking. But in my opinion it's a good show as it is now: it's refreshing. It's similar to a cop show, but it is unique because it's not about a cop, it's about a guy effectively functioning as a human Guinea pig for cops. It's a different perspective. It's about how his job, and the drug, affect his life.
It's not a Netflix show or an HBO show so don't go in expecting something like House of Cards... it's great for what it is, and that is a sometimes cheesy network show. I love this show and it's my favorite on TV right now, it makes me happy, and it's nice to watch after a long day. I don't know why people were expecting some sort of break out crime drama rated MA because if you recall the film that this show gets its premise from was mediocre at best. There's nothing wrong with this show that can't be summed up by saying that it's not your cup of tea. If you like happy, funny shows, with realistic and dimensional characters and quick-witted scripts, then you'll like this show.
