I loved seeing Sonic Tails & Knuckles on the big screen! Although I know it's a kids movie, I think the Hawaii wedding/Save Sonic part was too long and ultimately unnecessary. The same goes for the bar scene. The writing for those two scenes could have been a lot better.
Other than that, everything else was great... well some of Jim Kerry's scenes where a little too over the top and a bit cringe. Again though, everything Sonic, Tails, & Knuckles was great!
Definitely worth going out to see (if you're vaccinated) with the family or some friends that joy video games (especially Sonic's), or silly adventure flicks.
