If this did have anything to do with his Twitter, I think that's a crappy decision. There are a ton of us who just come here for videos and don't generally give a toss what people say on Twitter-- I don't know if it's the format or the userbase, but Twitter seems to bring out the idiot in people. I care that the man has interesting things to say about movies, sometimes things I disagree with, sometimes things I'd never have considered at all, but interesting takes on movies. I've seen a couple of films I wouldn't have otherwise bothered with because something in an Escape to the Movies intrigued me, and I'm not a big filmgoer. I still love his video introducing the Guardians, and my husband and I re-watched it right before watching GotG. That kind of encyclopedic comics knowledge is definitely not something you get out of a standard movie critic.
On the SJ stuff... I'm a feminist and I guess I'd be seen as an SJW as I'm strongly opposed to GG, but that said, sometimes I do think Bob was on the wrong side of the performative rage line, especially for an ally (when you get that consistently hulk-ragey about non-life-and-death things that don't affect you, I start wondering if you're doing it mainly for the buzz of righteous anger). Some of his conclusions I think are just daffy, especially the Halo-blue-eyes thing. I think he lets himself get trolled too much, I think he'll take some kind of angle on something (like that Halo thing) and think it's persecution of people don't agree with him, and I hope he learns to moderate that. *Most* people I've seen get really into SJ eventually burn out into something more sensible and that early "mad at everything" thing passes. ...but all that said, the man has interesting opinions about movies, that's what makes him watchable, and I think the Escapist is shooting itself in the ass to lose this many good original content producers.
(Also, sign me up for the "if Yahtzee goes, so do I" brigade. Jim, Bob, EC, and Yahtzee kept me coming here too. With most of them gone, I only see coming here every week or two for Yahtzee. I miss when this place was a multiple-visits-a-day site for me but it hasn't been that for a long time.)
