When my primary movie-going companion and I decided to commit to two all-night movie marathons a month ago, we were not really sure what to expect. But after last weekend’s mostly-successful All-Night Horror Show, I was pretty sure I could get through the “All-Nighter on Elm Street” – consecutive screenings of the first seven entries in the saga of famed Springwood Slayer Freddy Krueger (played exclusively by Robert Englund in these films) – without too much trouble.
