Part of why he got the gig is that he's been writing about the MCU literally for years, with some of the only coverage I've seen that tries to actually evaluate it through a critical lens.If I wanted to just read someone's opinion of a show there are countless posts online I can read. If you are a paid reviewer then I expect you to bring at least some objective standards to your review. I'm not saying large portions of it can't be subjective, obviously, but those subjective portions need to be grounded in at least some kind of objective reality. And here, I would argue it is objective that episode 4 does not "jog in place", regardless of it you actually like how the plot progresses.
Its like the equivalent of having a reviewer who only loves RPGs review the next Madden game. Sure, its subjective, but is it really going to have any kind of credibility? That's why professional reviews need to look at things a bit more objectively than the average person.
I like episode 4, but his core point is that everything before the final 10 minutes is reiterating beats we've already seen, which I think is at least worth engaging with.
