The Title
This isn’t so much technology as much as it is the people behind it giving the special the inclusive name of Holiday Special. Sure, Life Day is basically Christmas (what with a giant Christmas tree and all), but they gave it the all-inclusive moniker of "Holiday" at a time before the devastating "War on Christmas". Luckily for them, they never put out a red cup and made everybody lose their minds. The special was already offensive enough as it is.
In conclusion, do I highly recommend you watch this special? Yes, because as a Star Wars fan, this is still important. It’s got the original cast (a feat you could never do today with, say, Jennifer Lawrence and The Hunger Games), it shows you where Star Wars was at when it first came out, and it introduced Boba Fett for wookiee sake! I will say that, when it starts, you should watch it with a fresh mind away from your Star Wars knowledge. Think about being a casual viewer in 1977 who’s never seen a Star War before and then see if this is what would sell you on getting into the franchise. The answer is a hard no, but still, you be the judge. When you watch it in the link at the beginning of this article, be sure to keep an eye out for Princess Leia’s phone call and take her advice. Even Carrie Fisher had to get drunk to get through this one, and so should you (21 and over only, please)!
