To be fair Twitch having lots of screamlords hamming it up for views and Giant Bomb coming off as unenthusiastic or overly dismissive at times can both be true.
Completely agree on this, the whole we got criticised for not being excited because we aren't loud felt like it was misrepresenting how GB could get in the past during E3. Just go back and watch the FF7 Remake reveal being accompanied by them going "No", shaking their heads and generally dismissing it with what can best be described as a collective eye roll.
Compare that to this year and them actually commenting on things they liked seeing from that game while bringing up points they were curious about in terms of how it would be handled. Even the weeks leading up to E3 have been more positive, I remember old Bombcast leading up to E3 being them groaning about it being that time of year again for weeks. Now, all credit to Jeff, every time E3 was brought up on a Bombcast he was quick to basically mention that while it is a busy week for them it's also a big deal and he was excited about it.
So yeah, in general I think during the period of time they were criticised for being unenthusiastic it was well warranted, but to their credit they listened and have been great in recent years.
Edit:
If I were to give any feedback this year, it would be more time given to the crews impressions on games that they saw on the show-floor or via appointments, so that we can get more in-depth detailed impressions. Think the likes of Easy Allies do a fantastic job in that respect and Waypoint was also great this year.
