This looks like it could be pretty cool especially if the movie's plot is similar to Ratchet and Clank: Up Your Arsenal's story line. I've started but haven't ever finished the other Ratchet and Clank games but I loved Up Your Arsenal's story and I honestly could see it making a good movie. I'm excited and I hope this doesn't disappoint.
The Ratchet and Clank games actually had some comparable characters imo but I think the characters in Jak and Daxter along with the story line just makes better sense for a movie. Basically the characters in Ratchet and Clank were good in the games, funny mostly, but I just don't really see them being in a movie for some reason.
I've never played any Jak and Daxter games but as far as my Ratchet and Clank knowledge goes, reasons that made it so popular was the crazy and diverse weapons, the comedy, the setting/cool levels, and the story, which can all be incorporated into a movie, and hopefully it will be. I may just be a fanboy, but I think that this could make a great movie.
