The story has been told many times: A siege of a police station. Where have you heard that before? Unfortunately, there is no other way, but this film has to be measured against the classic Assault on Precinct 13 by John Carpenter. And unfortunately it falls short compared to the 1976 original (and even compared to the 2005 remake).
There are attempts to introduce some (insignificant) subplots, but ultimately it is only about the said siege.
And here a few peculiarities are noticeable: firstly, there is the almost complete lack of weapons (we are talking about a station that is not supposed to be abandoned). Then the main character has full access to the Internet and telephone...but instead of moving heaven and earth to get help...No, she probably doesn't think of such things.
Finally, we have the main character who is severely handicapped by a leg injury...it is actually doubtful that such a person would be reinstated as fit for duty...even for a desk job.
