We really enjoyed the first Sonic movie after all the troubles with re-designing the main character (who was originally hit with the ugly-stick and only resembled Sonic if you really squinted). It became a huge box-office hit until the pandemic struck.
A sequel is in the making though, but that isn't the only filmisation of Sonic we have to look forward to. Netflix just revealed that Sega's fast running hedgehog is getting his own 3D animated TV series in 2022, Called Sonic Prime. It will be produced by Sega themselves, WildBrain Studios in Vancouver as well as Man Of Action (creators of Ben 10).
Hopefully something to look forward to.
