Answer:
So to clarify that sentence, we rephrase it to read:
After visiting the place the movie was filmed, I am sure it would be great.
Explanation
The original sentence in the question was not clear about whether it is the movie that visited the place where it was filmed or who is sure about the outcome of the movie.
A dangling modifier is an error in grammar where the modifying word or phrase or descriptive clause is attached to the wrong subject. In some cases, it's simply the absence of the subject in a sentence thus leaving room for a misunderstanding of what the sentence intended to communicate.
In other words, it leaves room for assumption. The goal of communication is to pass across a message in such a way that the recipient knows exactly what the giver of the information intended to communicate.
A modifier functions as a clarifier. It provides extra details about a concept.
For example,
Having finished the meal, Ziki turned on the Computer.
<em>"Having finished" </em>indicates an action but does not state the doer of that action. Left the way it is, the reader may assume that Ziki was the person who finished the meal.
There are several ways of correcting dangling modifiers.
1) Locate and identify a subject that best completes the sentence.
2) Ensure that the Modifier is very close to the Word or Phrase it
modifies
3) Convert two clauses into one coherent sentence
In the answer above, we inserted the pronoun "I" thus creating a logical subject that lends meaning to the initial statement.
Cheers!
