How can this be rated higher than Wedding Crashers?

Rating: 6/10 (20 July 2012)

Ted is a pretty funny movie, but it is by no means justified a rating in the high 7's. Going by what other comedies are rated, this deserves a 6.2 or so. It is of course predictable, and it makes you laugh out loud for about 15 minutes or so. What makes a great comedy? To me it is having classic lines that you and your friends will be talking about for years. Thats what happened with Wedding Crashers, Old School, Happy Gilmore, etc. This isn't in the league of those; and therefore I would like to see its rating settle down in the 6's. IMDb seems to have every other genre of movies rated correctly outside of Comedy. I don't see why people have such differing opinions and senses of humor.
