Not everyone will like it or give it a chance due to the last three failed films. I'm a fan of the movie, Arnie, and Linda at heart so I'm still excited.
I'm a huge fan of the first two. I love Arnie and loved Linda in the first two (and the tv show Beauty and the Beast with Ron Perlman). Unfortunately, as I have previously stated elsewhere, the last three movies have soured the franchise in my opinion. But, I will still go and watch it. I knew going in that Genisys probably wouldn't be good, but went to the cinema anyway to see for myself. I have the same opinion with this movie.
However, it's only a teaser trailer. Maybe the first "proper" trailer will blow me away and completely change my mind. But, for now, expectations are very very low. This is not to say I am trying to convince others that they shouldn't like this trailer or be excited for the movie. If they're excited then that makes me happy, as people getting happy about upcoming movies is always a good thing.
