->"''Sure as day follows night, sure as eggs is eggs, sure as every odd-numbered ''Franchise/StarTrek'' movie is shit.''"
-->-- '''[[Series/{{Spaced}} Tim Bisley]]''', played by '''Creator/SimonPegg''', [[HilariousInHindsight who starred in]] [[Film/StarTrek the eleventh Star Trek movie]], and noted the irony.

Various ''Franchise/StarTrek'' series have collected various groups within ''Trek'' fandom: Some will love a particular series, some will gush about almost ''anything'' to do with ''Star Trek'' at all, and some will vocally express their rabid dislike of a particular movie or series, and present a laundry-list of reasons ''why'' it's the worst of the lot.

And then there's the Star Trek Movie Curse.

In a nutshell, the ''Trek'' feature films have followed a peculiar pattern: even-numbered ''Star Trek'' films have always done well at the box office (with the exception of ''[[Film/StarTrekNemesis Nemesis]]''). Odd-numbered films, on the other hand, have either failed miserably or still succeeded, but had a few glaring flaws that kept them from that coveted "top spot".

Of course, all this is subjective and vulnerable to nostalgia (''I'' was a bigger hit than ''II'' at the time, for instance). Everybody gets a kick out of the Movie Curse itself, but there's much disagreement on which films constitute exceptions and how well the others fit. There are as many theories about the Curse as there are ''Star Trek'' fans.

This page covers all such curses in media where the good and bad entries are said to follow a pattern.

----
!!Examples:

* StarTrek: In the 20th century, the page-naming Curse was fairly consistent (to the point where ''Insurrection's'' crew made a point of calling the film "Nine of Ten" on set to stave off the odd number's influence). But this century the Curse seems to have gone off the rails -- 2002's ''Film/StarTrekNemesis'' flopped while 2009's ''Film/StarTrek'' was a hit, contrary to their positions in the series. It is unknown whether this anomaly means the Curse has actually been broken, or merely inverted.
** Among those who do consider ''10'' bad and ''11'' good, there are several commonly proposed methods to realign the curse with "reality". One is using the sum of the digits as an indicator, or alternatively including the AffectionateParody ''Film/GalaxyQuest'' as a ''Star Trek'' movie, inserting it between 9 (''[[Film/StarTrekInsurrection Insurrection]]'') and 10 (''Nemesis''), as [[http://qntm.org/odd put by]] [[Website/ThingsOfInterest Sam Hughes]]. Another theory states that ''Nemesis'' wasn't good because it was a multiple of five, and thus, like ''Film/{{Star Trek V|The Final Frontier}}'', was bad; in other words, the curse has a previously-undiscovered [[http://en.wikipedia.org/wiki/Fizzbuzz FizzBuzz property]]. This is followed by the excuse that ''Film/StarTrek'' doesn't follow the pattern because of the interference of [[HandWave time-traveling Romulans]] -- besides, it wasn't made by the same crew as the rest. Some have also taken to referring the [[ContinuityReboot reboot]] film as "''Star Trek 0''," thus placing it in an arguably even spot.
*** ''StarTrekVTheFinalFrontier'', ''StarTrekNemesis'' and ''StarTrekIntoDarkness'' share the distinction of being the only Star Trek movies '''not''' nominated for a HugoAward, although in the case of ''Into Darkness'' it may be a reflection on the level of competion, rather than a lack of quality on its own part (2013 nominees in its category are ''Film/{{Frozen}}'', ''Film/{{Gravity}}'', ''Film/TheHungerGamesCatchingFire'', ''Film/IronMan3'', and ''Film/PacificRim'')
** Michael Demtschyna, along with Chuck Sonnenburg of Website/SFDebris, have suggested the alternate theory that the movie is bad when any of the main characters sing. These are ''The Final Frontier'', ''Generations'', ''Insurrection'', and ''Nemesis'' (with Chuck snarking that ''Film/StarTrekTheMotionPicture'' doesn't contain singing only because [[LeaveTheCameraRunning it would distract from the boredom]]).
* Interestingly, the ''Franchise/IndianaJones'' franchise seems to be the opposite; odd-numbered movies (''Film/RaidersOfTheLostArk'', ''Film/IndianaJonesAndTheLastCrusade'') do well, while even-numbered movies (''Film/IndianaJonesAndTheTempleOfDoom'', ''Film/IndianaJonesAndTheKingdomOfTheCrystalSkull'') are nowhere near as good.
* The odd-numbered {{Beethoven}} symphonies are the classics (3, 5, 7, and 9. 1, not so much), whereas the evens (except for 6) don't get as much attention.
* Many fans consider the ''Franchise/ANightmareOnElmStreet'' series to follow the reverse of this, with the even number movies being inferior to the odds. Hilariously, it is still inverted to Star Trek with regard to reboot status, as the Nightmare reboot is considered poor by most fans, unlike the mostly acclaimed Star Trek 2009 reboot.
* Fans of ''Series/TwentyFour'' have noted that odd-numbered seasons are generally the show's better ones, featuring a variety of different terrorist scenarios, while the even-numbered ones always revolve around nuclear terrorism and are generally greatly inferior (except for possibly season 2, which is considered to have a solid core storyline, but let down by the subplot involving [[TrappedByMountainLions Kim constantly being taken prisoner]]).
* ''Franchise/PowerRangers'' fans have an unique version with anniversary seasons ''[[Series/PowerRangersTurbo Turbo]]'' (Season 5), ''[[Series/PowerRangersWildForce Wild Force]]'' (Season 10) and ''[[Series/PowerRangersOperationOverdrive Operation Overdrive]]'' (Season 15) considered among the worst or most divisive. Time tell will if ''[[Series/PowerRangersMegaforce Super Megaforce]]'' (Season 20, [[SequelNumberSnarl if it could be called that]]) continues the curse.
* MicrosoftWindows has had the curse since Windows 3.1, at least when it comes to their major public releases. Windows 98, Windows XP, and Windows 7 have all been popular, while Windows 95, Windows ME, Windows Vista, and Windows 8 all made rather controversial changes or were too unstable which made it difficult to recommend upgrading. Still, they each have their fans. Much of this may come from the fact that those versions of Windows often included radical changes at once. This either caused issues with the system or were just too different cosmetically that people were indifferent.
* The ''Franchise/AceAttorney'' series has two different variants of this trope:
** Firstly, the odd-numbered entries (''Phoenix Wright: Ace Attorney'', ''Trials & Tribulations'' and ''Dual Destinies'') are generally considered to be the stronger ones, while the even-numbered ones (''Justice for All'' and ''Apollo Justice: Ace Attorney'') are considered to be weaker. The two ''Ace Attorney Investigations'' games generally aren't counted towards this, as the second one has yet to be released outside Japan (and, in all likelihood, [[NoExportForYou never will be]]). Though for those who do the first is usually considered to be on the "weaker" side and the second on the "stronger" side, which makes the order problematic.
** Secondly, fans have noted that the third case in any given game usually tends to be the worst, mostly due to the overwhelmingly hated third cases in (ironically enough) the second and fourth games. ''Dual Destinies'' is the major exception, as most seem to regard the second case as the weakest; some fans also feel that the first game's first case is weaker than the third, for essentially being a glorified tutorial which doesn't even fully explain the game mechanics.
* While fans of the ''Literature/{{Temeraire}}'' series of books don't necessarily find the even-numbered books to be bad, there is definitely a pattern of odd being "war and lots of cool dragon battles" and even being "travel and lots of talking". However, both the sixth and seventh books are travel and diplomacy, and the eighth is Napoleon's Russian campaign.
* ''MyLittlePonyFriendshipIsMagic'' seems to be following this so far. While Season 1 is by no means considered ''bad'', it suffered from EarlyInstallmentWeirdness and a much more restrictive [[AnAesop Aesop]] format. Season 2 is generally considered to be where the show [[GrowingTheBeard grew the beard]], which was followed by Season 3 which is the most controvertial and poorly recieved on the show. ([[BaseBreaker especially the finale]]) Then Season 4 was mostly well-recieved. ([[{{HSQ}} especially the finale]])
