I think that a variety of different types of journalism and media should exist, but I do think that "hard-hitting" and "investigative" journalism are in anemic supply in an industry that desperately could use it.
I think my problem with "we're just fun guys making fun content!" is that it is so prevalent in comparison to the other kinds of journalism that...yeah, it can be entertaining but that's what the majority is now. And if it's not, for lack of a better term, unprofessional casual content then it's corporate speakboxes and hype machines.
A big problem with it is also probably that investigative and "smart" or "professional" journalism in games media probably doesn't pay as well or get you ins with developers to discuss or look at their content. Not like you'll be blackballed necessarily but if a journalist is asking you questions about shady business practices or shitty bullshots or the myriad amount of bullshit in the industry then why would any company talk to you or give you review copies or anything of the sort?
It's a shitty situation and I don't begrudge anyone for taking the route they take to succeed or enjoy their time in games journalism but whenever I see another group of people do stuff like this it's just kinda...well...okay. Sure. Guess that's fine.
Edit: Also, count how many times I used quotation marks and call me out on it. Damn yo.
