Even though these are pot smoker movies and this is the third one, I have a feeling people will either love this or hate this. The other two, while their stories were out there, were still based on reality. This one is in a slightly different universe where the actual events might make sense if you really were high.
It's also in 3D and the 3D is actually really good. It makes Avatar look Avatarded.
Overall not as good as the previous two, but still has many funny moments for fans of the series.
