I have not seen Zombieland, Basterds, or Hurt Locker, and I have a feeling they might be the best.
Instead of listing the same movies (Avatar, Star Trek, etc.), I will try to add a few that I did not see in the posts.
Youtube Star Wars Episode I Review: I actually liked the Phantom Menace when it came out. I almost missed some of my AP exams to see the movie on opening night, thus I did have high expectations. However, after watching the review, I do not know what I was thinking. Who is the protagonist?
Bigger, Stronger, Faster - Surprisingly good documentary. Came out in 2008, but I do not know many people that saw it until this year. It is an honest film about steroid use in America. If you are like me and grew up wanting to be Hulk Hogan, Arnold, and Rocky, take the time to see this film.
Worst Movie: Thankskilling While scrolling through the Netflix on demand horror films, I came upon this tripe. I knew it was going to be bad from the second I saw the cover. I was hoping it would at least be funny and have some classic one-liners, but "fowl play" does not cut it. For an hour and fifteen minutes I sat watching the time wondering when it would end. My wife and I made fun of it for days, so I guess it was good for something.
