My assertion that maybe he likes working in teams is not made up at all, it is referencing his storylines in the Clone Wars series where he does so more than once. In one set of episodes he is working alongside Aurra Sing and Bossk for example. It is therefore much more of a stretch to describe him as a loner based on the screen depictions of Fett. Only EU backs up that interpretation of Fett's character. Nothing in the OT explicitly shows that.
Do people here not watch and accept the fleshing out of Boba in the Clone Wars series? He does not read like the character many are describing here.
When I saw him in Mando his behaviour didn't strike me as odd at all, so I'm just wondering if most commenting are not as familiar with his other storylines and his greater character development in Clone Wars?
See going by TCW I totally get why you'd have no problem with Marvel "Team Up" Boba. I recently binged the entire TCW series and do remember him teaming up with Aurra Sing and others very well. IIRC he even showed apprehension about killing certain individuals that his more ruthless teammates had no such qualms regarding. So yes that too is a different Fett than what we saw in the OT. Which is why many of us outright dismissed it.
Speaking "canonically" you are indeed 100% correct that Mando Fett isn't too much of a leap from AOTC/TCW/OT SE Fett. I don't think any of us old timers would dispute that. I think that many of us were just hoping that Mando Fett would represent a continuation of his more nasty OT self rather than a return to the more noble/obedient TCW/OT SE version. Again if you go by *just the films* then even the wretched AOTC supports the notion that he's always been quite the jackass! A little kid laughing with glee at the attempted murder of a Jedi just doing his job? What a punk! The last thing I want to do is give AOTC props for anything (lol) but even that film showcased him to be quite the jerk.
