That's a valid concern but what's the alternative? Stop making Sonic movie?
Well... yeah! End with a high-note.
How many movie series do you know that were good for the first few films, but ended with a poorly received movie? To the point you wish they just stopped with the last one and leave it as it is.
Honestly, if Sonic 4 or CD turns out to be the very last film in the series, regardless if it's awesome or not, I can settle with that. The films had a good run, let's not stagnate them with obligatory sequels. Even if there's plenty of game-materials to work with such as Unleashed, Lost World or Frontiers, if Paramount starts running out of steam to produce these movies, it will begin to show in it's quality. And if Sega are not satisfied with the quality or response of the movies, they will likelty do the same thing they do with their games and pull the plug on it and not look back.
That's different for me. Somehow I'm hearing it in Jaleel White's voice.
I guess so, it's just I can imagine the slight raspy distort of Dreamcast-quality recording as Meow speaks.
