I assumed the sequel to Arthur would naturally sucks. Sequels or anything other than the original do not always stand up the first film or book, etc. Arthur 2 was surprisingly good.
The story is more fleshed out than the first film and it defiantly is meant to be more than just Arthur running around drunk. In some respects I think Arthur 2 is better than the first film, but I’m not confident enough to say that for certain. It defiantly is a great movie and would still be good if the first film didn’t exist.
Unfortunately the ending was kinda crap. It was anticlimactic and just didn’t live up the rest of the movie.
Ignore the fact that it is a sequel and watch it.
