Looked over the review for Trick 'r Treat- you still need a beta for your grammar and spelling errors. For instance, I'm sure that
Now the No potion
should be 'Now the No portion'. There's also some awkward and redundant wordings. It would have been nice to see more about each section and how they tie together, which is one of the things that I was intrigued and fascinated by.
Something to have been put in the cons is that they mention in the beginning of the movie that if you violate Halloween's 'traditions' you'll be punished, but the only tradition mentioned and then violated is that of the Jack-O-Lantern being blown out. The rest sent mixed messages about the traditions and the violations.
Your review for 'Paranormal Activity" has similar issues. There's incorrect punctuation from the beginning, and some incorrect usage of words. Since you bothered mentioning the low budget, you should maybe compare it's success to others that had similarly low budgets- and why this succeeds where they failed.
