I voted for dislike. If I was about three or four years younger, I would've voted for 'hate', because I was able to throw that word around so easily back then.
And also because as a kid, I really
did hate it. It completely ruined the magic of the first movie for me and for years I avoided this film like the plague, and denied it as being canon.
Fast forward to now--I still deny it as being canon, and I haven't watched it in about two years, but I can see the positives of the movie. They have nothing to do with the writing or the story itself. I think the animation is spectacular with some really gorgeous backgrounds. The score is by a man named Don Harper who is virtually unknown and it really is a wonderful piece of work, one I listen to very frequently. Lebo M provides some of his best work in this film in Timon's Travelling Theme. The voice acting is very good too, especially Timon, although it's hard to find a negative with Nathan Lane. There are several aspects of this movie that make it a far better sequel than Simba's Pride which is why I can't outright say I hate it, but these aspects have nothing to do with anything that I consider
important to building a solid, worthwhile franchise--at least Simba's Pride added to the timeline and didn't crap all over the original movie. (Not too much, anyway.)
The reason this movie is so bad imo is because it's a waste of time, and ultimately a missed opportunity. It's telling the story of two characters who are not that interesting and who were as vital to the plot as the hyenas and Zazu--but you don't see a movie about those guys. It adds nothing positive to the canon. It ruins the majesty of the Circle of Life scene and several others, and one thing that always bothered me is how the movie contradicts itself several times. How are we supposed to take it seriously when it gets so many things wrong with the original storyline, like the Can't Wait To Be King scene and the ending with the hyenas? I suppose that could be a sign to not take it as canon and to see it just as a comedy, but if it isn't, then it's just an example of very poor writing.
Timon and Pumbaa already had their own TV show. That was more than enough time to spend on them. There was absolutely no need nor any desire from the majority of the fandom to have a movie dedicated to these two. It's a blatant cash cow and really only caters to the fans of the original who never really cared about TLK that much, so it doesn't mean much to them to see the original movie made fun of to such an extent, or the magic of it being cast aside for fart humour.
A fun way to pass a couple of hours, but it's a meaningless movie over all and certainly not one I'd recommend.
