One can find out about new comedy movies on various websites that offer reviews and ratings as well such as Rotten Tomatoes, IMDB, RateThatMovie, and MovieNation.
Imdb (Internet Movie DataBase) usually provides ratings of each movie that they have an entry for. I have included a link.

YouTube Movies and Amazon are good places to start with. If one does not have prior knowledge about the actor, the website "IMDB" could provide a wealth of information as well as commentary and viewer ratings.
You can't watch films on that site.
According to IMDb the film "Sweet November" received mixed review ratings with an average of 6,4 points out of 10. So by the end of the day it was not bad, but also no blockbuster compared to other movies.
IMDB does not maintain its own list of the scariest movies of all time, but it does allow the sites users to create their own lists. Users of IMDB listed "Psycho", "The Shining", and "The Exorcist" as the scariest movies of all time.
Yes IMDB does provide information on the actress named Jennifer Siebel and what she has played in for movies.
