Turtles Forever is a TV movie that serves as both the final adventure for the 2003 Teenage Mutant Ninja Turtles, but also to celebrate the franchise's 25th anniversary. In this, when the Turtles go to the surface after Master Splinter finds news footage of heroes looking like them foiling a robbery, they arrive at the Purple Dragons' base, only to see the Turtles in question, who were captured, are the 1987 Turtles. Brought to the 2003 dimension after their last battle with their Shredder caused an explosion, now the two sets of Turtles, each with different personalities and logic, must find a way to fix things, especially when 1987 Shredder has brought back the 2003 Shredder, who proceeds to take over the Techodrome and plots to eliminate all turtles and rule the multiverse.
This movie teams the more serious 2003 Turtles with the more goofy 1987 Turtles, and it shows. The 1987 Turtles are always goofy and joking about (one of the main jokes is confusing the 2003 characters with their fourth wall breaks). Also, the movie manages to put some references to the 1987 show in, as well as characters from other series.
However, while it is good, it's not perfect. The 1987 characters all have new voice actors due to 4Kids not wanting to hire the original VAs due to them being a non-union company (and located in New York City, where the VAs in question are in Los Angeles, where some are retired while the rest are even signed with the Screen Actors Guild, which means they would refuse to do this due to not being sanctioned like most of 4Kids' other works. Also, 4Kids uses their own music, making a new soundtrack for the 1987 Turtles' dimension to avoid paying licensing fees to Lionsgate (who owned the rights to the 1987 TMNT cartoon at the time). So instead of Cam Clarke as Leonardo, we get Dan Green (who never sounds like Cam, as his voice is more like his earlier 4Kids role, Yami Yugi, the transformed form of the main character of the original Yu-Gi-Oh anime 4Kids owned at the time), while Sebastin Arcelus takes over 1987 Raphael from Rob Paulson (although unlike Dan, his voice in this is almost accurate to Rob's). In fact, Sebastian and Johnny Castro, the latter voicing 1987 Michelangelo in place of Townsend Coleman, are the only two replacement VAs that sound close to the original VAs.
Despite the voice actor replacements, music issues, and even some continuity errors, this is a good way to end the 2003 series. With a good story spanning different incarnation of the franchise, some neat action, and even some good humor, Turtles Forever may not be perfect, but it's a good end to 4Kids' incarnation of the mean, green fighting machine.
