Poor pg-13 out of rated R series

Rating: 1/10 (31 March 2011)

I do not see how they go from a good rated R movie series to pg-13 stale movie. I really like the first 3 movies. I went and saw this in the theater with jam packed first midnight showing that day before mass showing in theaters. Really regret paying the price for it.
The main character that took over in this can't remember his name because I just don't see how he could be that good for this kind of movie as the others. Any who this was the worst one out of the four movies. Not only the PG-13 deal, but the plot sucked and characters really did not draw me in as the others.
If they come out with 5th movie please go back to the rated R way and have a different main character. I like the first 3, just not this one at all. For all that rated this high. I hope you enjoyed it. I do not recommend seeing this more than once.
