inground pool? is it worth it?

we are looking at buying a house that has an inground pool. the pool is not finished. we are not sure if it has been finished at one point and the liner has been removed, or if it was never finished. the concrete, the patio, the steps, the diving board all are finished. when you look in the pool, you can see wood around the sides. you can see that the one end is deeper than the other. it of course has some green water in the deep end, but the shallow end is empty. it has grass and debris in it.

the size of the pool on the property data website is 16x32.

what are the differences in types of pool liners?

is getting this pool in working order going to be a huge mess or is it worth doing?

thanks in advance!!
