If you thought the original was bad, prepare yourselves, because this movie is, well, surprisingly a slight improvement over the original in my opinion.
What I still dislike about this movie is that unlike the first film this one focuses more on trying to be hip with the target audience with internet references, it retains the poor execution of such ideas from the first film including everything to do with Baby Corp, the toilet humor, the baby related scenes are still insufferable, it overuses tropes from a lot of movies despite being different ones, it relies a lot on pop culture references, an incredibly weak plot twist, some parts drag on for too long, this movie is as nonsensical as the previous movie in a bad way, a mediocre climax, weak villain, product placement for Mentos which feels very out of place for a DreamWorks movie, and everything feels very inconsistent.
I do still see some good qualities, including the fact that it does stay true enough to the 2017 movie by retaining all the elements that made it the movie it turned out to be, the characters are much more likable this time around, Tim is much more relatable considering the situation of adulthood, some jokes work, the animation and voice acting is still good, it has better morals than the first, okay musical numbers, decent soundtrack, and the ending is written a lot better than last time.
Overall, I thought this was only one step ahead of the original, despite it still not being that good of a film at all. I would not recommend you see this movie.
