Heres both of the trailers:
The first trailer doesn't make much sense with that "30 years ago" part at the beginning. This movie is a full reboot and not a sequel, so those events from 30 years ago never happened in this time line. This movie looks like it could be fun, but something seems a bit off with it. Aside from casting all women, it feels like a rehash of the original property without giving it something really new to focus the reboot around. The new weapons could be cool.
