"Semi-Pro" is nothing like Will Ferrell's other films. It is not nearly as good as "Elf", or "Stranger Than Fiction". The reason I say that is because it was very corny and unfunny at many moments. Will Ferrel's performance was not nearly as good as it could have been. It felt like the director tried a bit to hard to be funny. Other than that, the film was very good.
The story revolves around a semi-pro basketball team. They are one of the worst in the league but are still trying to get into the NBA. The team is ran by the main player "Jackie Moon" (Will Ferrell). His motives are not what you would say top notch, so They hire a new guy and try several other things to become NBA Material. It eventually works after going through hilarious processes.
The film's plot is a very basic concept with some flaws here and there. I would say it is worth watching for the most part.
