When I first encountered pure land buddhism, it's definitely the feeling I got. Once you really investigate and read about great realized beings such as Nagarjuna, Vasubandhu, Shandao, Honen etc. who all practiced and advocated the pure land path your doubts start to minimize to a certain degree. I still have doubts from time to time but it can always be overcome with practice and study. Unlike all other Buddhist schools, the pure land school is a purely faith based path so doubts are normal. Having said that, there are many ways to experience Amida Buddha and his Pure land right here as many masters have done by means of practices outlined in the pure land sutras.
