Early in the MCU, fans used to say that a lot about the first Thor movie, oddly enough. Ragnarok is obviously a much better movie, but I basically agree in both cases. The Thor/Loki dynamic is a big part of it. The early Thor films weren't great as films, but it was always fun watching the two of them. Ragnarok has grown on me a lot, I didn't love it initially, I guess because it's almost a parody at times, but it has many hilarious moments, cool visual design, and some great action sequences. Definitely a fun movie to rewatch, it never drags.
