I only watched half, but it's really good for a fan film.
And everyone blames everything on bad acting.
Well guess what? If the actors say something silly, it's bad scripting. If the actors do anything wrong, it's actually the director's fault about half the time.
Directors do a lot more than sit around and yell "action" every time filming starts. In rehearsals they actually pretty much tell the actors how to act their parts. If there's anything wrong with the acting in rehearsals, then the director is supposed to catch it and tell the actors to do it differently. It's all about the director's vision, and if the director can't tell the difference between engaging dialogue and a robot reading a script, well it's not just the actors' faults for not being good actors, it's the director's fault for not telling them what they were doing is wrong.
I think the script made the dialogue seem like, well, someone reciting a memorized script. Like that part where that investigator lady is talking about how Gotham is sick of Batman, her acting was fine IMO. It was the script that made it sound very unnatural, like a pre-meditated speech.
So the actors aren't great, but the script could use some work, and the director could have been less lazy about letting crappy performances and scripting make it to the final film.
Overall, it seemed very professional, and was better made overall (acting, scripting, directing, and production) than most "Sci-Fi Original" movies on the sci-fi channel...
