Topic: What's the Worst Thing You've Ever Seen in Cinema?
The question at hand is, "What's the Worst Thing You've Ever Seen in Cinema?". We mean this in a technical or artistic manner, not "what's the most morally dubious thing ever displayed on film", but rather, "what's the biggest artistic mistake you have ever witnessed in a movie". This can be poorly done opening titles or closing credits, it could be a terrible green-screen job, maybe it's a terrible acting job, or anything else which just screams to you that this doesn't seem like the quality one can expect from Hollywood's around 100 years of experience in the field of making movies.
If you want to describe a particular scene, or post a screenshot either would be great.
Hopefully this turns out to be an interesting discussion!
