Saw another review talking about the "magic" of the first film and how (basically) this movie is a disgrace to the "good burger" name but... come on.... the first movie wasn't really that great either. Ya im sure I enjoyed it more cause I was a kid and if I let myself be blinded by nostalgia I would hate this movie in comparison but both movies have the same ridiculous plot, silliness, corny acting, and over the top childish humor.
I actually kinda enjoyed watching it even though it definitely doesn't deserve anything above a 6/10 - the first movie had some special charm but let's not pretend it was a masterpiece. I actually expected this movie to be really bad so I went in with low expectations but about halfway through I realized it's actually pretty spot on quality wise when compared with the first movie.
That "special charm" of the first movie probably had everything to do with the time it came out and the fact that I was a kid then and that's the target audience! Sure there were some really memorable scenes from the first one but if I really go back and analyze I can't say it was really thaaat much better than this. I'd say the 1st was 6.5/10 (probably a 9/10 in my kid brain) so only a little bit better - I rewatched it in recent years and remember being really underwhelmed and thinking "this didn't age well" and "this was all so much better in my memory."
Point is... its about what you would expect.
