Hannibal. Face, BA and Murdock are back.
As far as the characters, I think these 4, especially Liam Neeson (Hannibal) and "Rampage" Jackson (BA) did better in their roles than the original cast. They brought the necessary qualities to the characters to make them engaging.
As with the series, The team is set-up and framed for something they didn't do, and are on the run while trying to find and trap the real bad guys. (I was able to figure out the bad guy this time :) There wasn't a great deal of dialogue, it was very often one-liners.
As far as the plot and story, it was very comparable to what you would have seen in the series. The story was told in a very fast-paced style, which I thought made it more enjoyable. There was lots of action, and some violence.
Although there was violence, there wasn't much gore. The language wasn't very bad, although there was some cursing. It is probably fine for teenagers, but you might want to take smaller children to something else.
