Why is everyone bashing the Prequels so much?
It is one thing that one personally dislikes them, but this kind of subjective judgement doesn't do justice to the people who like them.
I for one think Ep. I is the best Star Wars movie, not because of the best plot, but because of the best execution. Contrary to the mainstream belief, there have been a lot of ships in Ep. I filmed from real models (for example the Radiant, the transport ship, the Naboo starship, the droid command ships etc.), and they look great. I would buy a kit of one of those ships.
I do understand that the CGI in Ep. II and III was overdone and ages strongly, but even that doesn't make the ship designs bad. I would love to build a good kit of for example an Eta fighter, an ARC fighter or the different versions of the star destroyers. Also the vehicles from the battle of Geonosis would be very welcome.
That the Revell kits stay in the hobby shops has other reasons in my opinion, mostly that they don't attract serious modelers because of their scales and the bad quality, and that kids like playing with other toys more.
I really hope that Bandai does some nice Prequel stuff.
