I was horrified by this film
Not because I'm easily squeamish, not because I was completely naive to the fact that in the time this film was made animals were killed quite calmly and, to quote my mother, the victorians and those that came shortly after could be quite bloodthirsty in their pursuits of 'fair game'. But this literally shocked me to the pit of my stomach because It was FILMED- which is rather sickening that this footage could then be used for entertainment purposes (as all film, even documentary has entertainment purposes).
I was shown this in a media lecture as an example of 'two-shot film' with no warning beforehand that what we would see was distressing: which rather made it seem all the more heartless. From the modern day analysts view you can see why it provokes such strong reaction, the camera is perfectly placed for the most disturbing shots and it creates the feeling that the camera is the audience's eye, it makes you feel like you're standing there witnessing such an event and unmoving, it gives consequently, rather a cold and brutal impression not just of Edison but of the society as a whole.
It's made all the worse when you know beforehand the year in which it is shot- because you know that it is real. If you watched animal cruelty in later films, which are all in colour, it mayn't produce such a strong reaction because you know that it's not real- it's all just pretend-like theatre.
