This was one I think I was slightly disappointed in when I first saw it in theaters back in '89 and even with subsequent viewings on VHS and DVD, however I've come to appreciate it more over the years post-2000s. Lots of fun though feels disjointed at times going back and forth in time from 1985 to 2015 to alternate 1985 and back to 1955. But I did like the technical aspects re-creating the events of the first movie. 4.0/5
PS: Still remember back in the day seeing a TV special and believing the hoverboard was real, lol.
