I decided to watch '18 Again' because I'm a huge fan of '17 Again'. Needless to say, this is more enjoyable than 17 Again. I loved everything about this. I love how they incorporated different things to make it even more enjoyable but not once allowing the viewers to get sidetracked. The acting was amazing (probably a few cringy moments here and there but every movie has that so I can forgive those). The OST was great.. i found myself getting emotional every time I heard it. i found it to be very beautiful and very fitting.
If you haven't decided whether or not to give this a try this is your sign. DO IT.
