"Knowing" starring Nicholas Cage. It couldn't pick a genre or stick to it and then had an ending that was ridiculous to the point of being laughable. With Rabbits.

Manos: The Hands of Fate.

"Life is about movies; anything else is a bonus!"- Me   

I'm going to have to go with the Sam Raimi Spider-Man movies.

Well I'm already up to 2 movies I really enjoy mentioned.

I think I'm just gonna avoid this thread from here on out. I'm not sure I can control that little voice in my head that wants to argue, with so much to disagree about going on here.

"Cracks" is pretty bad.
Also starring Eva Green, and surprisingly Matt Smith, is "Womb", which is another example of how to not do films.
Both perfect examples that actors alone does not help bringing a movie up in goodness. Matt Smith and Eva Green are both excellent thespians, but both movies are horrifically bad.

I don't have a single film I like the least, or even a bottom 5 - I don't hate film for being bad, as much as missing potential. Some films I really didn't enjoy:

The expendables
Batman forever
Iron man 3
Promethius

Wow, decisions..decisions. Like most, this thread isn't capable of holding the plethora of terrible films that get the green light. I could include any film with Eddie Murphy, the Joel Schumacher Batman films, any of the Friedberg & Seltzer movies, along with retarded science-fiction films like Apollo 18 & that supposed Alien prequel (fuck you Ridley Scott!).

However, for me the cardinal sin in film-making is shear laziness & incompetence and the piece of shit film that was the worst film experience of my life is Movie 43. An anthology comedy movie that is completely devoid of any semblance of humor in it. The film's biggest crime it commits is not that it's relies entirely on offensive (and racist) gross-out humor, but that it does it with a cast of A & B list across that hacks like Friedberg & Seltzer could only dream of employing. While F&S have Carmen Electra, Drake Bell, and Kevin Sorbo; Movie 43 has Hugh Jackman, Halle Berry, Naomi Watts, Kieran Culkin, Kate Winslet, Gerard Butler, Kristen Bell, Chloe Moretz, Richard Gere, Elizabeth Banks, and Patrick Warburton, just to name a few.

Movie 43 is a movie whose humor can't supersede the mentality of a 4th grade boy and even with all those talent actors, they created a film that will make a 10 year-old boy cringe more than laugh. Like Teague said during the Apollo 18 commentary; "You (Apollo 18) tried to shit on my face and you shit on my neck...you can't even do that right."
And this movie has wasted enough o
