The actors being replaced and the CGI being so different has just ruined it for me. I'm only 10 minutes in and already want to turn it off.
All the other Ice Ages were great. The story lines did become more and more unrealistic but nonetheless enjoyable, but it's the actor's changing for me and different picture quality. They haven't got that spark in the characters anymore that makes the characters who they are.
I know they say it's due to COVID reasons so then why bother making another movie? Best stopping at Collision Course, 6 years since a show being created is too long of time in between a sequel so things change and actors change...
