Its watchable

It was entertaining for a very corny sci-fi.

Aliens seem weak for their level of technology - they were interested in Earth 65 million years ago. However, the Earth oceans will be evaporated in 1.1 billion years. Not a long term plan for a species living on that kind of time scale with millions of years to develop technology and infrastructure. Might make more sense to build orbital structures - but that wouldn't make a good action movie.

The movie has cringey far-left western ideals. Villain is a white male. They try to defeat the aliens with kindness, diversity and strong female lead.

I seen no strategic advantage in becoming allies with the Grey alien turncoats. The prisoners of war greys seemed to be more helpful in constructing weapons and sharing technology.
