Sure there's violence, but nothing in this is horror. I assume that's why it's rated so poorly. Either that or the people who gave negative reviews don't have a sense of humor. What this is is an incredibly entertaining and funny time travel action comedy. Even if you don't watch the rest of the series (I haven't yet), you'll definitely miss out if you don't watch this episode. Whoever wrote this deserves way more credit than I'm sure they're getting. I imagine this would have fared much better if it had instead been uploaded to one of those YouTube short film channels. The 13 minutes just fly by.
