Compare to Hibiki, Kabuto, Den-O, Decade and especially Double, Tsuburaya always had better CGI. Devilman and Cutey Honey were also horrible.Ultraman Cosmos movies were great for their time. Every Kamen Rider movie suck in term of CGI, they are just extension of TV episode. Please, Tsuburaya always has better CGI than Toei, from the beginning it's always like that.
Only Casshern and GARO can impress me, most Japanese movies suck in term of special effect, tokusatsu or anime. The effect for the shocker grunt bomb in AllRider suck hell.
And even if Tsuburaya weren't at the forefront before, they are now, according to the consensus of people who watch it. Even people who dislike the movie still praise it's special effect.
