Likewise, I saw this on CN...but I saw it on May 21. And in many respects, I wish I didn't. The plotline was too straightforward, and all the characters were too flat.The anime graphics and the CGI graphics clashed terribly. I also say that Suicune didn't get enough spotlight in the movie...and it was running SLOW...just slow. It does provide evidence for one thing, though: Under the correct circumstances, the Beasts will allow humans to ride them. That scene was done well, unlike everything else in the movie.
Basically the movie was a learning experience about Suicune, and nothing more. It confirmed everything I had hypothesized about Suicune, except for two things: one, its actual top running speed; and two, its ability to heal other life forms (by around 6,000 HP. :P)
