Aside from the re-casting the whole crew, my problem is that the characters personality was changed from the first 3 movies, e.g. Susan becomes a bullied rather than a protective and caring mom. She also a technophobic and sticks to the old school, which feels unnecessary compared to her in the previous films. Also, Rowley didn't have enough screen time, his only appearance was 3 minutes and towards the end of the film. Lastly, Rodrick is my biggest gripe, he went from a Bully and later becomes buddy with Greg although in the previous films they were rivals and arch enemies, I gave this movie a low rating, not because I'm a nostalgia blind from the first-three movie, but its actually that they should never make a sequel without the original cast.
