5. Butterfly Effect 2...and 3
The Butterfly Effect has become a cult classic to many, even with Aston Kutchers dodgy acting and questionable special effects. This has caused filmmakers to cash-in on its success and bring out two sequels. For an average thriller film, this is quite impressive. Yet the original is a masterpiece in comparison to these cheap spin-offs. Whilst number three has some redeemable qualities in that it goes for a more horror-genre feel to mix things up, the second film is extremely dull with even worse acting, a tired storyline and cheap visuals.
Why its in the top 10: The worst quality of all films in this list. A snooze fest where its only thrill is laughing at how poor its craftsmanship is.
