I just can't stand when people make negative assumptions based by misinterpreting things. I'm not expecting it to be Indiana Jones, but i'm not gonna go out of my way to crap on it 15 months before it opens. That irks me a lot (obviously).
Mission Breakout has been getting some of the highest guest satisfaction scores in Disneyland history (between both parks), soo i'm not sure why any fans would have trepidation..
In fact GOTG: MB, is very much so a reason to be excited about ANY Marvel attractions. Regardless of the size of the building, or what new tech is in play. (and remember how much fans crapped on that ride when it was announced?)
