Some of you may be wondering how, with the previous AVP movie proving to be so forgettable, a sequel could be regarded as a disappointment. But before its release, the Strause Brothers made all the right noises about Requiem’s new direction; rather than chase the PG-13 action figure crowd, Requiem would be harder edged and R-rated, the directors said. And Requiem was harder edged, with a quite gruesome opening which involved a spacehugger and a small boy.

Unfortunately, the film was also full of tedious teen drama scenes straight out of Hollyoaks, some murky cinematography and a ridiculous new cross-breed: the Predalien. This new lifeform represents everything that was wrong with the Alien Vs Predator movies; it mated two very different franchises and produced a new entity which made a mockery of its forebears.

I Am Legend (2007)

Before you leave an angry comment at the foot of the page, bear this in mind: I Am Legend is probably one of the better, if not the best, film on this list. But Francis Lawrence’s expensive adaptation of Richard Matheson’s classic novel still counts as a disappointing film because it was so close to being great – its opening, set in a post-plague New York gradually being reclaimed by nature, is wonderful to behold, in spite of its CG animals.

It’s when the nocturnal Darkseekers came crawling out of their homes that I Am Legend began to falter. The novel’s creepily intelligent, virally spawned vampires were replaced by an army of bald, screeching wall-crawlers with distracting lower jaws; having carefully built up an aura of tension in its opening hour, I Am Legend quickly retreated into more familiar Hollywood territory. The movie would have been improved somewhat had the originally intended ending been left in – one that invested the Darkseekers with a greater amount of humanity – but the film’s over-reliance on CG robbed it of the vitality it initially possessed.

The Invasion (2007)

Don Siegel’s Invasion Of The Body Snatchers is undoubtedly one of the greatest sci-fi movies of all time. Remarkably, Philip Kaufman’s 1978 remake of the same name was almost its equal, and there was also much to admire about Abel Ferrara’s 1993 version, simply entitled Body Snatchers. Unfortunately, 2007’s The Invasion proved to be one remake too many.

Entirely lacking the air of paranoia that permeated the three previous movies, The Invasion replaced pod people with a virus which controls humans from within. And like an alien imposter, The Invasion was but a soulless facsimile of those earlier, better films, with character names and entire scenes replicated to severely diminished effect.

Downfall director Oliver Hirschbiegel’s initial cut of The Invasion failed to pass muster with studio executives, and so the Wachowskis and James McTiegue were ushered in to respectively rewrite and reshoot certain chunks – to the reported tune of $10 million.

It’s difficult to say just how much of an improvement these reshoots made to the film, but The Invasion’s box office receipts told their own story. Grossing just $15 million domestically against an investment of $80 million, The Invasion’s financial performance was almost as disappointing as the film itself.
