As well as ranking the episodes "best" to "worst", the marathoners also kept a running tally of classic occurrences that happened throughout the series. Go to the end of the video for all the results. Amazingly Spock's Brain WASN'T the worst!
The crew behind this marathon have done 5 movie marathons in the past, the longest being a 3-day, 25-film James Bond marathon and a 2-day, 11-movie Star Trek movie marathon. We wonder where Star Trek Into Darkness would fall?
