I wouldn't watch it even if the trailer was really good but....I'm gonna shit on it for looking awful, not being targeted towards adults. That opening green screen shot looks AWFUL. I said in another thread it reminds me of those old car commercial edits with the Mark guy. The perspectives of the camera vs the background don't seem to fit
All they would probably need to do is replace the main cast with digital game characters, or at least something that's rendered so they at least blend in a lot better.
It almost seems like the Sonic movie thing, where they first released a trailer that was so awful they had to change Sonic to look much better. I'm still not sure if it was a very expensive marketing move or not.
