Most of the very low budget
The Asylum movies are absolutely atrocious. They mainly bring out extremely low budget sci-fi and/or disaster/apocalypse movies and many are their own awful version of a major blockbuster release under a slightly different name. For instance, just before the blockbuster disaster movie
2012 came out in 2009 they released
2012: Doomsday which confused a lot of people (although this was apparently their answer to the blockbuster 2008 movie
Doomsday) and their answer to the more recent blockbuster movie
Gerostorm is
Geo-Disaster, so don't be fooled. I believe that loads of people have sat down expecting to watch what they believe to be an excellent high budget blockbuster movie only to be confused and scammed into watching a dreadful imitation of it by The Asylum (okay some may have downloaded it from "dodgy" sites).
The Asylum movies are so bad that if you watch one of their many apocalypse movies and look at the background you will very often see blatant things that definitely shouldn't be there, for instance during complete devastation you will often see a highway in the background with fully intact traffic moving along normally, on one I even saw a normal worker in a yellow jacket casually going about his business in the background when the few surviving main characters were apparently running for their lives to avoid being wiped out by an apocalypse level ice storm that had already wiped out most of the planet. There's far too many mistakes to mention and the filmmakers surely must realise, yet they obviously either don't care or they're running on such a low budget that they can't afford any retakes. The movies also come with awful acting, dire scripts, masses of plot holes and very poor CGI effects. In fact many of their apocalypse movies are virtually same script, E.g. there's government officials / military that make all the wrong decisions and are later about to make matters much worse with a plan to stop the disaster, while there's nearly always a family (often with an estranged teenager) along with some off beat professor or doctor that knows exactly what's going on and that the official plan to stop the disaster will be catastrophic (no-one will listen), but against all the odds they always manage to save the planet with some ridiculous and totally unbelievable plan just in time before the officials finally finish the planet off, after nearly being wiped out themselves throughout their journey on multiple occasions of course by abysmal CGI effects (that's supposed to be the most exciting part).
Okay so far I've only named a movie company and not the worst movie I've ever seen, to name just one is very difficult as there are so many awful The Asylum movies, but if I had to choose one I will choose:
War of the Worlds 2: The Next Wave
It probably isn't the very worst The Asylum movie they ever made, but it was the most bitter disappointment after watching the blockbuster movie
War of the Worlds from 2005 staring Tom Cruise that I watched in the cinema. I didn't know this apparent sequel was an abysmal The Asylum effort and not a true sequel to the first movie (well apparently they made a first movie too) and it was obviously absolutely dire with the usual terrible acting, script and very poor CGI effects bundled with masses of plot holes + mistakes. I suspect most people only watched it because they thought it was a real sequel, but The Asylum get many of their viewers by scamming people into believing they going to watch a blockbuster movie instead. That said The Asylum are so bad at making movies that they've now got a cult following and they were also fairly successful with
Sharknado and it's various sequels (I hate it).
Here's a review:
It also shows some examples of the many flaws and plot holes that found that are always found in The Asylum movies.
