The movie was fairly interesting and could keep you watching the entire move however it is a decent movie and not that great in my opinion. The animators and graphic designers truly worked hard on the visual appearance of this movie and it is impressive how the characters look in the remastered movie and it looks very good on HDTV however despite those positive features the movie does have some drawbacks.
One of the negative features is the main plot. The plot of the movie was not well thought and it wasn't that great, two extraterrestrial warriors as powerful as Frieza heading to Earth isn't that interesting as anyone of the Z Fighters could have defeated them and it was taken more as a joke than a serious threat which decreased the action level and intensity of the movie and as evidenced that they could have been easily beaten Super Saiyan Goku was able to quickly dispose of Abo and Kado (The main antagonists) in the end.
Another negative feature in this movie is how easily the main antagonists who at first seem truly evil end up being easily converted to good after being offered radishes and are shown eating happily with the Z Fighters. That contradicts their initial personality during the movie's battle.
However a positive feature is the battle Abo and Kado had with some of the Z Fighters as the fighting was good, the effects were impressive and the action did not slip however it should be noted that the main antagonists are simply as powerful as Frieza and even Gotenks as excessively cocky as he is should have been able to kill Abo and Kado fairly easily.
I also enjoyed the introduction of Vegeta's estranged brother and how shocked the Z Fighters were when discovered that Vegeta has a younger brother. It was quite surprising how Vegeta's brother Tarble was gentle and kind instead of being like the average Saiyan: brutish and evil. What the creators didn't do well was the scene where Android 18 states that she senses a great power and it turns out to be Tarble who was heading for Earth and his power was not even greater than that of Raditz and it was a great exaggeration on Android 18's part.
The humor and comedy in this movie was good especially the scene where Hercule finds himself baffled as to what the name of his new hotel is however there is a slight detail in the movie that does not fit, Videl mentions God in the near-ending of the movie however in the DBZ Universe the main deities seem to be the Kais however that may be of her knowledge as she possibly does not know of the Kai's existence even though she is married to Gohan.
Overall the movie was fairly decent and I give it a rating of "Decent, Normal or Below Average" because of the weak plot, the ridiculous main antagonists and their sudden heal turn at the end of the movie. I'd give the movie 5 out of 10.
