There was an interesting video made by space/avionics industry engineer pointing out technical mistakes made during the filming of the LEM descent, specifically the LEM was travelling second-stage forward in low lunar orbit while landing which would be impossible, hence it's necessarily a fraud and sloppy-executed special effects using miniatures.

The design of the Apollo-era LEM is completely implausible as you'll see by comparing it to recent redesigns. We're supposed to believe these early LEMs functioned flawlessly yet the new redesigns are different by orders of magnitude in every respect.
