Just when you think this series is done they come out with another sequel pretty much out of nowhere. I don't have a problem with that of course as I have enjoyed all the previous films. A lot of the actors return again with a few who were replaced here and there. Mike Thurmeier has returned once again from the last two films as well as recent shorts. This is the first time Galen T. Chu has directed a film of the main series after only writing the first one. Michael J. Wilson returns to write this after only being involved in the first one. Michael Berg once again returns to write this after only missing part two. Yoni Brenner returns after being only a part of part three and a few shorts. This is the first time Aubrey Solomon has been involved in the series. Anyways now it's time to see if this will be as enjoyable as the others have been. It starts out with a Scrat short of course. Who doesn't love that adorable little guy. Poor Sid always gets dealt a terrible hand. Oh Manny you are so lucky. Haha the grape juice effects though. Simon Pegg is awesome as always here with a really fun character. Max Greenfield is hilarious as a newcomer to the series. He has a good knack for voice overs and should definitely do them more often. The gags and jokes are pretty fun. There are a few jokes that are inappropriate here and there. Some of them can be a little edgy. I ended up enjoying this one just as much as the other ones. The new characters were great and the old characters were still interesting. The Neil deGrasse Tyson stuff was amusing. I think it's a fun one for the whole family. I really don't see what there is to hate about it honestly. If you've sort of grown up with the series I'm sure you will enjoy this one too.
