Time Shift #2 of Phineas and Ferb
15 January 2012 | by (United States) – See all my reviews

So I thought this episode was quite interesting. The entire episode was a parody of Lord of the Rings. At this point in their TV series, I believe that it is very sad to have to steal another movie's ideas. I realize that the director is from family guy in which has parodied many movies in it's history, but most kids who are watching this show will not get the reference and the audience they are trying to appeal to, will most likely not like the randomness of it. The only reason I gave this episode more than 1 star is because it was kind of humorous in the way a kids show is trying to rip off a classic movie. All in all, this episode was very corny and could not possibly appeal to kids.
