G Gundam is probably one of the most controversial entries in the Gundam franchise, and the reason is obvious: it does not follow the real-robot, war-drama scheme of most Gundam shows. Instead, it opts for a complete super-robot feel. In a sense, it is Gundam only in name.
The series revolves around Gundam fights, where pilots use their bodies to fight each other in giant robot ring-fights. Characters yell out special moves in an over-the-top fashion, and the overall feel of the series is lighter and goofier. This is the reason a lot of fans find it hard to take G Gundam seriously.
Though, if you can look past all of these things, G Gundam can be a rather entertaining romp. Domon and his God Finger technique are always exciting to watch, and he can really be a breath of fresh air if you are not very fond of the traditional whining teenager. In the end, opinions will be very divided. Fans will either learn to appreciate a deviation from the traditional formula, or reject it completely, considering it a blemish on the franchise.
So, what do you think? Is it an unnecessary entry in the series, or is it an acceptable change of direction?
