Nah, fifth dimension was incredible. It had a proper story to it that flowed with the ride and was told with humour. The effects for the time were fantastic. I don't doubt that by now it would have aged horribly if not frequently update with more modern effects (imagine!!), but as a ride experience it was a huge downgrade for me.
I don’t doubt Tomb was more popular overall though, it had a clearer theme that set appropriate expectations for riders.
Don't forget that because of how old it is and the technology at the time all the pov's are really poor quality, especially as low light recordings. It was something to experience, not watch.
