If the history of Hollywood has proven anything, it's that audiences have shown themselves to be incredibly fickle. They beg and they plead for a movie to get made, but then never even bother supporting it when it hits cinemas.
Now of course, the reality is a little more nuanced than that, but there are a number of long-requested films that a lot of people wanted to see, only for everyone to categorically turn their backs when they finally came out.
The reasons for this are myriad - perhaps the film was poorly marketed or the reviews were terrible or the studio simply waited too damn long to make it, but in each case fans failed to turn up for a movie they insisted had to be made.
To make it sting worse, most of the films on this list are also pretty good, such that they actually deserved to enjoy some well-earned box office success, rather than tanking catastrophically and having to settle for, at best, selling some DVDs or being rediscovered on streaming.
Everyone was enthusiastic about these films out of the gate, but by the time they finally hit cinemas that excitement had long since faded, for shame...
10. The Lego Movie 2: The Second Part
The Lego Movie was one of the biggest cinematic surprises of the last decade - a shockingly clever and creative tribute to those teeny plastic blocks we all love, rather than the crass, cynical commercial exercise it could so easily have been.
The film was consequently a stonking box office success and a sequel was soon enough announced, with The Lego Movie 2: The Second Part finally releasing five years later in February 2019.
Though there was considerable initial excitement about the sequel announcement, The Lego Movie 2 cratered at the box office despite solid reviews, grossing just $192.4 million worldwide - a mere 41.1% of its predecessor's $468.1 million haul.
The reason for its failure has been dissected by box office analysts ever since, some blaming same-y marketing which failed to distinguish it from the first film, others citing the five-year gap between movies, and perhaps most persuasively the ever-troubling notion of "franchise fatigue."
The Lego Movie 2 was actually the fourth entry into the Lego Movie franchise, with Lego Batman and Lego Ninjago films being released during the aforementioned five-year gap.
Though Lego Batman was a solid success, Lego Ninjago bombed at the box office less than 18 months before The Lego Movie 2's release, seemingly ensuring that all the initial excitement around a second mainline Lego Movie dried up, killing the franchise.
It's a damn shame, as while failing to meet the highs of its predecessor, The Lego Movie 2 is a respectably enjoyable animated sequel.
