You should try to watch good movies.
You use the term “good” as though it is quantifiable. Cool if you don’t like the teaser ─ I wasn’t particularly jazzed about TFA’s trailer while everyone else seemed to really like it; to each his own. However, I fail to see the point behind your continued posts in which you express your dislike for the teaser. What’s your goal: to convince others who do like it that they’re wrong to like it? To let everyone know you don’t like it? If the former, it’s a pointless exercise, so why bother? If the latter, mission accomplished, so no need to keep belabouring the point.
Personally, I’m quite pleased at what I’m seeing ─ Rogue One is hitting all the right notes for me.
